These forward looking statements may differ materially from our actual results, and we are under no obligation to update these statements. In an effort to provide greater clarity in the financials, we are using both GAAP and non GAAP financial presentations in both our press release and on this call. A reconciliation of these non GAAP financials to the most directly comparable GAAP measures have been included in our press release, in our slide presentation and on our website atrampus.com on the Investor Relations page are under financial releases. We adopted ASC 606 in 2018 using the modified retrospective method, which did not restate prior periods, but rather ran the cumulative effect of the adoption through retained earnings are at the beginning balance sheet adjustment. Any comparison between our results under ASC 606 and prior results under ASC 605 is not an accurate way to track the company's progress.
We will continue to provide operational metrics such as license billings to give our investors better insight into our operational performance. Discuss our financial results, including our guidance for future periods, and then we will end with Q and A. I'll now turn the call over to Luc to provide an overview of the quarter. Luc?
Thanks, Jess, and good afternoon, everyone. Q2 was an exciting quarter for the company. We complemented our excellent financial performance with a number of strategic advancements to capture the next wave of semiconductor growth focused on next generation data center architectures. This quarter, we delivered $84,900,000 in quarterly revenue and $51,600,000 in cash from operations, are meeting expectations for the top and the bottom line. In addition, the company launched our CXL in cell memory interconnect initiative announced the acquisitions of PLDA and analogX and initiated a $100,000,000 accelerated share Each of these activities grows the size and scale of our chip and IP businesses and puts the company in a great position to utilize on the next wave of semiconductor growth in data centers.
As we have discussed before, Rambus sees a tremendous opportunity to lead the market and accelerate the adoption of CXL InterConX in next generation data centers. CXL is going to be a critical enabler for memory expansion and pooling in disaggregated and composable architectures. Through our CXL memory interconnect initiative, Rambus is leveraging our unique combination of technology, experience and expertise to develop breakthrough solutions to these new high performance use cases. The acquisitions of PLDA and Analog X strengthen this initiative by providing critical building blocks for high bandwidth chip and subsystem interconnect solutions. The complementary CXL and PAM4 based interface solutions augment our interface IP offerings.
And when combined with our existing interface and security IP, we have all of the necessary ingredients to be an industry leader in CXL and PCIe IP as well as offer differentiated CXL based interconnect products. Turning back to this quarter's performance, We continue to consistently meet or beat financial targets. Our balanced portfolio of chips and Silicon IT continues to scale and will continue to drive growth in the coming quarters. Product revenue from memory interface chip remained solid with another quarter over $30,000,000 in revenue, and we expect record product revenue in Q3. Silicon IP revenue was up 10% quarter over quarter, bolstered by a number of design wins as the industry continues to build solutions for data center and AI.
Demand for our memory interface chips continues to be robust. We have sustained momentum in DDR4 and a strong market position in DDR5. We have received orders and have started to deliver production DDR5 memory interface chips to the market. On the supply side, We are now seeing some of the shortages and cycle time challenges experienced by our peers in the semiconductor industry. We are actively managing our supply chain are working closely with our partners to ensure our ability to satisfy the growing customer demand for our products and support the aggressive memory interface tube revenue targets we set at the beginning of the year.
This quarter's performance also saw saw performance in our Silicon IP business with record revenue from security and digital control IP. The demand for Silicon IP remains strong, particularly in high performance data center and AI applications, where the growing need for bandwidth and security and compressed product development timelines, are accelerating the need for trusted and reliable off the shelf IP. The acquisitions of Northwest Logic and VeriMetrix have delivered extremely well and provided blueprints for successful integration as we bring Amelio X and PLDA into our Silicon IP business. In addition to the strong performance from our businesses this quarter, we continued to make great strides in the communication of our environmental and social programs. We are committed to responsible and sustainable practices.
And as a fabulous semiconductor provider, We know that one of the biggest impacts we can have on the environment is through the selection of our partners. With that, We have joined the Responsible Business Alliance, an organization dedicated to corporate social responsibility in global supply chains. Our formalized governance structure and oversight committee ensure that our policies and actions align with our passion for creating a safer have a more sustainable future. The health and safety of our global workforce, customers and partners remain our top priority. We are actively monitoring the human impact of the global pandemic and are appropriately responding in each of our geographic locations.
In closing, the company had an excellent second quarter. We took some very important strategic steps to accelerate our roadmap and grow our market position. Rambus is uniquely positioned to address the critical challenges facing the industry and remains on the forefront of next generation data intensive architectures. We continue to grow faster than the market are taking the right steps to support the company and our customers as we increase in size and scale. There will be new challenges as we continue our transition to a leading product company, and I'm very excited about the many opportunities in front of us this year and beyond.
With that, I'll turn the call over to Rahul to discuss the quarterly financial results. Rahul?
Thanks, Luke. I'd like to begin with a summary of financial results for the Q2 on Slide 8. Once again, we delivered a solid quarter with financial results at the high end of expectations and generated $51,600,000 in cash from operations. Now let me talk you through some financial highlights on Slide 9. We have consistently realized profitable growth over the past many years.
This has enabled us to invest in strategic initiatives, return capital to investors and improve cash from operations and free cash flow. We've built a strong foundation for future growth. Let me walk you through our non GAAP income statement on Slide 10. Revenue for the Q2 was $84,900,000 above expectations. Royalty revenue was $41,900,000 while licensing billings were $65,200,000 The difference between licensing billings and royalty revenue primarily relates to timing as we don't always recognize revenue in the same quarter as we bill our and customers.
Products revenue was $31,200,000 consisting primarily of the buffer chip business. Buffer chip revenue was slightly below the midpoint of and would have demonstrated growth if not for a shipment delay at the very end of the quarter. Contract and other revenue was 11,800,000 are in line with the Silicon IP business. As Luke noted, we were delighted to report quarterly records for the digital controller business we acquired from Northwest Logic and Security IP. Our execution bodes well for the integration of the 2 acquisitions that we announced in June.
Overall, the Silicon IP business grew over 10% quarter over quarter. Total operating expenses, including COGS for the quarter, came in at 56,100,000 Operating expenses of $43,700,000 were lower than expectations due to the timing of certain discrete R and D expenses. We expect to grow investments in our product roadmap, including through acquisitions in the coming quarters to drive our long term growth. We ended the quarter with headcount of 592, roughly flat from the previous quarter. I expect headcount in Q3 to increase as we integrate the strong engineering talent from Analog X and PLVA.
Under ASC 606, we recorded $2,400,000 of interest income are related to the financing component of fixed fee licensing arrangements for which we recognize revenue, but not yet received payment. We incurred $800,000 of interest expense, are primarily associated with our convertible note. This was offset by incremental interest income related to the return on cash and investment portfolio. After adjusting for non cash interest expense on the convertible note, this resulted in non GAAP interest and other expense for the quarter of 1,600,000 consent for non GAAP pre tax income. Non GAAP net income for the quarter was $23,100,000 With continued focus on cost and disciplined execution, we delivered profit that was nicely above expectations.
Now let me turn to the balance sheet details on Slide 11. Our ability to generate cash has helped us to both invest in growth drivers and consistently return capital to shareholders. End of quarter cash, cash equivalents and marketable securities totaled $477,100,000 down from the previous quarter as Cash from operations of $51,600,000 was offset by the $100,000,000 accelerated share repurchase program we initiated in the quarter. As we deliver on the top line and execute on operational efficiency, we expect to continue to deliver strong cash from operations in the future.
At the
end of Q2, we had contract assets worth $324,000,000 which reflects the net present value of unbilled AR related to licensing arrangements for which the company has no future performance obligations. I expect this number to continue to trend down as we bill and collect for these contracts. It's important to note that this metric doesn't represent the entire value of our existing licensing agreements as several customers have royalty based agreements that allow us to recognize revenue each quarter. 2nd quarter CapEx was $5,800,000 while depreciation was $5,100,000 We delivered $45,800,000 of free cash flow in the quarter. Looking forward, I expect CapEx for the Q3 to be roughly $5,000,000 I continue to expect depreciation of roughly $20,000,000 for the full year of 2021.
Now let me turn to our guidance for the Q3 on Slide 12. As a reminder, the forward looking guidance reflects our current best estimates at this We've also been providing information on licensing billings, which is an operational metric that reflects amounts invoiced to our licensing customers during the period, adjusted for certain As we have reported historically, licensing billings closely correlates with what we had historically reported as royalty revenue under ASC 605. Under ASC 606, we expect revenue in the Q3 between $76,000,000 $82,000,000 We expect royalty revenue between $25,000,000 $31,000,000 and licensing billings between $59,000,000 $65,000,000 As Luke mentioned, this outlook represents record revenue for the Bucklecher Like many others, we are now starting to see some of the strain in the semiconductor supply chain, but as of now are maintaining our lead times and delivery commitments to our customers. We expect Q3 non GAAP total operating costs and expenses, which includes COGS, to be between $65,000,000 $61,000,000 as we increase investment in programs. Our guidance includes incremental expense from Analog X, which we closed in July, but we don't expect any incremental revenues due to acquisition accounting.
Our forward looking projections do not contemplate PLDA, which we expect to close later this quarter. Under ASC 606, non GAAP operating results for the Q3 is expected to be between $11,000,000 $21,000,000 profit. For non GAAP interest and other income and expense, which excludes interest income related to ASC 606, we expect approximately $1,000,000 of expense, which includes $600,000 The 24% is higher than the statutory rate of 21%, primarily due to higher tax rates in our foreign jurisdictions. As a reminder, we pay roughly $20,000,000 of cash taxes each year, driven primarily by licensing agreements with our partners in Korea. We expect non GAAP taxes to be between an expense of $2,000,000 $5,000,000 in Q3.
We expect Q3 share count to be roughly 113,000,000 basic and diluted shares outstanding. Overall, we anticipate a non GAAP profit per share range We've made substantial progress strategically, operationally and financially. We've realigned our portfolio to address opportunities in the data center and to support long term growth. Our product businesses are well positioned in the market and we anticipate long term growth in each segment. Q2 was an excellent demonstration of our successful capital allocation strategy.
Will continue to invest organically in products like DDR5 and our CXL initiative, make inorganic investments like analogX and PLDA and return value to our Before I open up the call to Q and A, I would once again like to thank our employees for their continued teamwork and execution resilience during these uncertain times. Everyone, please stay safe and take care of yourself and your families. With that, I'll turn the call back to our operator to begin Q and A. Could we please have our first question?
Thank you
for holding.
Your first question comes from Gary Mobley with Wells Fargo Securities. Your line is open.
Good afternoon, guys. Thanks for taking my question. I I
want to start off by asking about CXL and your approach there. First question is, when would you expect to productize CXL or how should we think about the different phases of the productization of CXL whether relate to IP, licensable IP and then eventually chip related revenue. And then Specific to 2 acquisitions, which help form a portion of the basis for the CXO initiative, how should we think about the Revenue contribution from each of those, maybe not so much in the near term, but when you don't have the purchase accounting headwind and then as well the related expense to those
2. Gary, this is Luke. Great questions. So for us, CXL, with CXL, we kind of Kill 3 birds with one stone. First, it improves our IP offering for memory expansion and disaggregation For anyone who wants to build chips for that market, so that revenue from IP is going to start almost immediately post acquisition.
People will buy IP, integrate that IP into their products and address the safe sell market with those products. So that's the first Bert, if you wish. The second thing is we are going to be able to use that IP in building our own semiconductor products. And that's critical because these CXL products are complex, especially in terms of latency and having the IP in house is critical for the successful development of those products. Those products will take a few years to develop and will hit the market in about 3 years from now and ramp from there.
So there's going to be a second wave of revenue coming from the CXL products themselves based on that IP. And the third aspect, which is not related to revenue growth, is that in these times of war for talents, the acquisitions of these The company allows us to bring very talented engineering teams into Rambus. So it serves Three objectives for us, bringing talent on board, increasing our IP revenue in the short run and are increasing our product revenue in the longer run. And we expect these two acquisitions combined to bring about $20,000,000 of accretive revenue in the 1st year.
Okay. Appreciate all the color. And as my follow-up question, I'm interested to hear, I'm sure others as well, What sort of a logjam there was on the chipset business, the buffer chip business late in the quarter and What steps you took to fix it and to what degree do your Q3 buffered ship revenue, To what degree does that contemplate any additional supply chain constraints? Thank you.
So first of all, I would say that we've been able to manage our supply chain quite well over the last few years By building redundancy in the supply chain, we grew the revenue, as you know, from about 36 €1,000,000 in 2018 to €140,000,000 last year. So we've seen the supply chain constraints later than some of our competitors. And now what we see, we see some pockets of supply constraints across different products. And we're working very actively and we have great support from our suppliers have to make sure that we address each one of these potential challenges immediately and that we don't disrupt are ready to serve the market and the demand, which continues to be very high. We do see across the supply chain people increasing their lead times or some pockets of shortages.
And as I said, it affects different products in different ways. But at this point in time, we're working very actively with our suppliers to make sure it does not disrupt The demand that we see ahead of us. Thank you.
Your next question comes from John Pitzer with Credit Suisse. Your line is open.
Yes. Luke, just a follow-up on Gary's question on the supply side. I guess, how much better could your product revenues have been in the September quarter? And I guess, importantly, as you look into December, Do you see some incremental supply coming on such that it's pretty clear that you'll show sequential growth on the product side in the December quarter as well?
I'll start great question. I think for the Q3, we are able to manage The situation, this is short term and we have great visibility of what we can do. So we feel comfortable with the Q3. With respect to the Q4, we just have a lack of visibility. I think we continue to improve the situation with our suppliers.
But between the pockets of challenges with suppliers and the transition between DDR4 and DDR5, It's difficult to predict what Q4 is going to be. But what I would say is that our design win momentum continues, Our backlog for DDR5 continues to grow very fast. Demand for the products continues to work and the support from our suppliers is there. It's just difficult to predict what Q4 is exactly going to be at this point in time. I believe we feel quite confident with our Q3 number.
And then, Luke, on the DDR5, I think Micron on their earnings call talked about DDR5 perhaps ramping a little bit later than they thought next I'd be curious to kind of get your thoughts on the DDR5 ramp. And I guess importantly, what kind of revenue adder that be to you either on ASP and or market share? And do you have a sense of how much the market could shift to DDR5 as an exit trajectory at the end of calendar year 'twenty two?
So yes, we heard about the potential delay of DDR5, but what's happening in the ecosystem is that people are building systems ahead of the launch. So we do see very solid orders from all memory customers that products that they ship to their own because the ecosystem, despite the potential delay, is building the systems to be able to run the products. So it has had very little impact on our order book or on our backlog, and that's a good thing. We expect to see a price increase when we move to Vigar5. We see this as part of our backlog.
And as we said in earlier calls, our footprint on DDR5 is quite strong because we started early. So When it ramps in the market, we should actually see our share continue to grow. So we've consistently grown our share in DDR4 over the past few years, but we're going to see a step increase in our share when DDR5 comes to production. At this point in time, we have a strong backlog. We received POs from the 3 of them.
Their customers are building systems in anticipation of the ramp of DDR5. So from that standpoint, all looks good. We'll see when the actual launch is going to happen.
Great. Thank you.
Your next question comes from Sidney Ho with Deutsche Bank. Your line is open.
Great. Thanks for taking my question. So a couple of questions on the memory buffer chip side. I know you don't want to talk about Q4 guidance yet, But what kind of revenue expectations do you expect from DR5 Chipsets? And second question, I know you talk a lot talk about 3 waves of memory TAM expansion, potentially doubling the TAM by 2025.
Can you maybe talk about what are the sizes and timing of these various waves that's going to happen over the next few years?
Sure. So on the first question about DDR4, HiSeq. The first question on DDR4 versus DDR5, As I said, we have little visibility over Q4. But what I can say is despite the talks about potentially delay of DDR5. We see our mix between DDR4 and DDR5 in a favorable way are in favor of DDR5.
So we're watching the mix as well. But as it looks today, the mix looks favorable to DDR5. But I think it's due to the that the ecosystem, despite the potential few months of delay, is building products for that market. And as I said, for Q4, we will watch the mix and we'll work with our suppliers to make sure that we don't disrupt any shipments to our customers. With respect to the product growth, we see the TAM doubling by 2025.
This is If you add buffer chip with the other interface products based on CXL, so that's the combination of these 2. And as I said, the CXCL ramp is going to start in 'twenty three, 'twenty four type of timing. So that's where the market today is around $600,000,000 $620,000,000 in size. So that market is going to double from that number By 2023, 2024. And there's a reason for that.
As we explained in earlier calls, this is the need from the Cloud service providers to have access to more capacity in terms of memory with lower latency. So that creates the need for either memory expansion use cases, which is going to be the target of our first product in that product line or for memory disaggregation or are recruiting, which is going to be the 2nd wave in that. So we do have a road map of products For the CXL initiative, we're starting with the first product, which is going to be a CXL memory expander, which will address
Okay, great. Maybe my follow-up question is on the Licensing and billings, if I'm not mistaken, I think typically a 3rd quarter is the strongest, usually up about 5%. Are curious why licensing billings in your guidance will be lower this year given the strong utilization in the industry. I understand you don't recognize any revenue from analog It's because of purchase accounting and you probably don't have anything in PLDA as in the guidance. But just curious, is it typical for Q3 for you guys to have could see a decline in billings and billing licensing billings.
Sidney, hi. Good question. What I'll tell you is that any given quarter, we're perpetually in the process of renewing partners. And so what ends up happening is that just based on How we structure those contracts, you can see licensing billings fluctuate from a quarter to quarter perspective. And that's often done kind of at the end of the deal negotiation, Just in terms of as our partners are working with us in terms of how they want to structure the financials.
The other piece of it is that from a licensing billings perspective, We've seen more of our silicon IP revenue show up in licensing billings this year than we'd anticipated. I think coming into the year, I thought it'd be closer to 20 I think now it's probably going to be closer to 40. And so as we print that number, you could see some fluctuation just depending on how our Silicon IT contracts are structured as well. The base of our business, I think, is just as strong as we always thought. We still have that Patent Licensing business that continues to be very strong, very predictable.
We've had some great renewals in the first half of the year that continue to support Our belief that that will stay somewhere between a $200,000,000 to $220,000,000 business for the next several years. Our silicon IP business also is growing very I think as we mentioned earlier, it grew 10% quarter over quarter and that shows up in a combination of contract and other as well as So I think that's the way I look at it. I wouldn't read too much into the quarter over quarter change.
Okay, very helpful. Thanks.
Are on your touchtone telephone. Your next question comes from Mehdi Hosseini with SIG. Your line is open.
Yes. Thanks for taking my Question. When I go back to the growth opportunities, a bigger picture, it seems to me that you would need to have DDR5 implementation for other opportunities like CXL to materialize. But Once there is a change in architecture, then there will be several different growth driver. Am I thinking about this right?
Or CXL could stand on its own. In other words, can is there anything with silicon IP And a growth driver that could be viewed as independent of DDR5.
Great question, Mehdi. At a high level, a CXL memory expander have a CXCell interface in the processor side and a DDR interface on the memory side. So it will come as a complement to our buffer chip business. Our buffer chip business will sit on the standard memory interface of the processor. And once this is fully populated and the CSPs need more memory, Then you will attach more memory to the CXL bus.
So the CXL bus will attach itself to the CXL product. And on the other side of that product, you're going to have a standard DDR interface. And that's why it was strategically important for us are to bring those IP on board because we do have a complete set of critical IP that allows to both develop the next generations of standard buffer chips, but also to develop those memory expanders that will help in the process has addressed more memory than they can do on the standard of us.
I guess what I'm trying to understand is, let's say, If the CPU company is late with their CPU upgrade, can other CPU or GPU based vendor or ARM based CPU chips that are coming to the market enable adoption of a new memory architecture like either DDR5 or CXL or both. I think there is some confusion around Sapphire Rapid, and I'm just trying to understand how your growth opportunities are tied to introduction of Sapphire Rapids.
Right. So I'll start with the end with Sapphire Rapids. The Sapphire Rapid is going to feature DDR5 standard memory interfaces. So that bodes well with our DDR5 bucket chip offering, and this is what's driving the growth that we're talking about for the quarters to come. Will also show some PCI Gen 5 and CXL 2.0 interfaces.
So those interfaces are going to be are available in the ecosystem, if you wish, both from Intel and AMD. So the mainstream in digital processors are going to pool the market to use potentially those interfaces. And then I'll follow with the First part of your question, with people developing GPUs or specialized CPUs based on other cores, What they're trying to do is they're trying to address a portion of the market that with very have data demanding use cases. And what these people could do is they could align to the same are PCI Egen 5 and CXL 2.0 type of interfaces, which would be good for them because if they do that, they know they can interface to develop all the product development ecosystem. So what they could also do is they could accelerate that road map and move are faster to CXCL 3.0 or PCI Egen 6.
And this is another reason why We did these acquisitions of Analog X and PLDA because they are advanced in the development of these next generation of CXL, CXL 3.0, and they are advanced in the development of next generation 5, like the PCA Agent 65. So by acquiring these companies, we will be able to address the needs of people who develop specialized processors for data intensive use cases in addition to the mainstream business.
Right. And just a final comment, I guess, given what you just laid out, perhaps a year from now, Your revenue volume would be different than what we're dealing today. Like a year from now, there will be Relatively a more broader diversification because of what you just said. Would that be a fair statement?
Maybe that's exactly how I look at it. And as I was talking about earlier, we have a very stable, predictable patent licensing business that gives us fantastic cash flow that, as I mentioned earlier, allows to invest organically, inorganically and continue to do capital return. You see wonderful growth opportunities for our silicon IP businesses. As we mentioned in Q2, we We had records for the controller business we bought from Northwest Logic as well as for our security IP business. And then you also see the growth Trinity, not just in the buffer chip, but as Luke mentioned in the future, it's going to be in CXL.
So certainly in 3 years from now, you'll see more on the I think next year you'll probably see also growth in IP in particular. So I think we're set up pretty nicely to continue to grow And across our portfolio in the coming years.
Got it. Thank you.
At this time, there are no further questions. This concludes the question and answer session. I would now like to turn the conference back over to Luc Seraphine.
Thank you, everyone, who has joined us today for your continued interest in Tyme. We hope each of you stay safe and healthy, and we look forward to speaking with you again soon. Have a great day. Thank you.
