In a joint press release issued early this morning, SK Hynix and Intel have announced that Intel will be selling the entirety of its NAND memory business to SK Hynix. The deal, which values Intel’s NAND holdings at $9 billion, will see the company transfer over the NAND business in two parts, with SK Hynix eventually acquiring all IP, facilities, and personnel related to Intel’s NAND efforts. Notably, however, Intel is not selling their overarching Non-Volatile Memory Solutions Group; instead the company will be holding on to their Optane memory technology as they continue to develop and sell that technology.

Per the terms of the unusual agreement, SK Hynix will be acquiring Intel’s NAND memory business in two parts, with the deal not expected to completely close until March of 2025. Under the first phase, which will take place in 2021 once all relevant regulatory bodies have approved the seal, SK Hynix will pay Intel the first $7 billion for their SSD business and Intel’s sole NAND fab in Dalian, China. This will see Intel’s consumer and enterprise SSD businesses transferred to SK Hynix, along with the relevant IP and employees for the SSD business, but not any NAND IP or employees. Similarly, while SK Hynix will get the Dalian fab, the first phase does not come with the employees that operate it.

Following the first phase, Intel will continue to develop and manufacture NAND out of the Dalian fab for roughly the next four years. This period is set to last until the rest of the deal fully closes in March of 2025. At that point, SK Hynix will pay Intel $2 billion for the rest of their NAND business. This will finally transfer all of Intel’s NAND IP and related employees over to SK Hynix, along with the Dalian fab employees. Intel and SK Hynix have not offered any explanation for the prolonged acquisition, so we’re hoping to find out a bit more with the companies’ relevant earnings calls this week.

Meanwhile, Intel will continue to hold on to their Optane memory business. Optane is considered a “platform differentiator” by the company, as Intel intends to continue leveraging the technology for their unique, high-capacity NV-DIMMs. Accordingly, Intel has announced that they will be continuing to develop the underlying 3D XPoint technology and sell products based on it, which is consistent with their long-term aspirations of making Optane its own tier in the memory/storage hierarchy.

Overall, selling off their NAND business is a big step for Intel, a company that started out making memory. But it’s not entirely unexpected, as Intel has never been quite as successful with their NAND business as they would have liked. And the core of the company’s NAND efforts, their longstanding IMFT joint-venture with Micron, started winding down in 2018 when the two companies announced that they would stop jointly developing flash memory.

Since then, Intel has largely been walking its own path, securing the #5 spot in the NAND industry (generally right behind #4 SK Hynix) and releasing new products, but struggling with the commodity nature of the NAND business. While Intel’s Non-Volatile Memory Solutions Group (NSG) as a whole brought in $4.4B in revenue for 2019, the group has lost money for 4 of the last 5 years, recording flat or negative operating incomes. Only in the last six months has Intel made any real money off of NAND, reporting $600M in operating income for the first half of 2020. So although NSG – and by large part, Intel’s NAND business – have played a big part in Intel’s record revenues, they haven’t turned a significant profit for a company that’s renowned for their 60% gross margins.

Meanwhile for SK Hynix, the Intel deal opens the door to some new opportunities, and it also helps formerly fourth-place company company scale up to deal with the competition of its three remaining rivals, Samsung, Kioxia/WD, and Micron. TrendForce estimates that once this deal closes, SK Hynix will become the second-largest vendor of NAND, with over 20% market share, placing it behind market leader (and rival Korean firm) Samsung. Like many other commodity component markets, the NAND flash market has been subject to wild swings in profitability and the resulting pressure to consolidate, so by picking up Intel’s NAND business, SK Hynix will be in a stronger position going forward.

But the real pearl for SK Hynix is Intel’s enterprise SSD business, which the company specifically calls out in its joint press release. Despite its overall modest size, Intel’s NAND business has a major presence in the enterprise SSD market thanks to its early investment there as well as its domination of enterprise CPU sales. Intel’s chief (and arguably only serious) competitor in this space has been Samsung, so acquiring Intel’s SSD business makes SK Hynix that much more capable of going toe-to-toe with their biggest rival.


Intel Enterprise "Ruler" SSDs

Long term, however, it remains to be seen what SK Hynix will do with the NAND fab side of Intel’s business. While it’s clear that they have big plans for SSDs and intend to leverage Intel’s existing market share and customer relationships – which is a big part of why they’re acquiring that segment first – SK Hynix doesn’t necessarily need Intel’s NAND manufacturing technology. SK Hynix is plenty capable of building more fabs on its own if it wanted more raw NAND capacity, and indeed the company has undergone several expansions. Meanwhile the companies’ technologies are significantly different, as Intel relies on floating gate tech while SK Hynix uses charge trap tech. So although the two technologies have their trade-offs, it’s very questionable whether SK Hynix wants to continue developing both over the long run.

And for both parties, the long run really is the key. NAND flash is still facing a likely dead-end in the long run, as NAND has been scaled down almost as small as it can go before leakage becomes a serious problem. 3D NAND stacking has given NAND a second wind in the interim, but there’s only so far that can go, especially in respect to reducing bit costs. Which is a big part of the reason why Intel developed 3D XPoint to begin with, as the technology doesn’t suffer the same scalability restrictions. So although Intel is getting out of the NAND game, they are still very much in the storage game over the long run, now focused on a non-volatile memory technology that is expected to scale much further in the future.

Speaking of the future, Intel has also stated that they will be investing the expected proceeds from the sale into some of their other non-core, forward-looking businesses. Intel’s 5G, AI, and edge efforts are all slated to benefit from the sale, and all are markets that Intel is priming for potentially extreme growth over the coming years.

In the interim, however, the next step will be up to regulators. SK Hynix’s acquisition will need the approval of American, South Korean, and Chinese regulators, which the companies expect to take around a year – and at which point SK Hynix can start the actual acquisition. Meanwhile Intel is set to announce its Q3 earnings this Thursday, at which point we may hear a bit more about the deal from Intel’s perspective. SK Hynix’s own earnings call will follow in a couple of weeks, on November 3rd.

    2001: "process nodes are reachign their limits with 130nm, 90nm si so small that quantum tunneling will thwart any further attempts to shrink nodes without changing to materials too expensive to use for proceesors.

    1980: "8MB hard drives are pushing the limitations of what is possible with spinning magnetic media. 10MB is too unreliable and its likely hard drives will never reach 20 MB

    If this inndustry has taught us ANYTHING, its that when someone says it cant be made smaller it gets made smaller within like 2 years.

    Yeah, they'll continue to stack and MLC and PAM and add LP-DRAM to grow density and speed. In the consumer space, the "storage" requirements aren't nearly as a concern as the cloud/enterprise space; so NAND is still viable for the foreseeable future to the consumer. Reply

    Within 2 years? Like 14nm got replaced by 10nm in only 2 years? Reply

    Nobody said 10nm is impossible. Also if you take a look at TSMC they indeed did their jump in about 2 years. Reply

    If you recall, TSMC's 7nm brings them to parity with Intel's 14nm. Reply

    Wow! Used to be the Intel crowd were claiming TSMC 7nm had parity with Intel 10nm. Now it's parity with Intel 14nm.
    Next year I expect it will be parity with Intel 22nm, and TSMC 3nm is what's needed to match Intel 10nm...

    Define "parity".
    The definition Intel was keen on for many years (right up until things went horribly wrong) was transistor density. By that metric 7nm matches Intel 10nm in specs (both are about 100 MTr/mm^2)
    with the important difference that TSMC has actually shipped a variety of products at that density (eg Apple and Huawei SoCs) whereas the best Intel has shipped on 10nm has less than half the claimed density, and the newest 10nm has a density even lower.

    I was speaking in terms of performance (IE GHz). Reply
  • ballsystemlord - Wednesday, October 21, 2020 - link

    Oh, in case you want to point out that AMD's CPUs only go to 4.9GHz (last gen was 4.7GHz IIRC), compared to Intel's fastest at 5.1GHz, Intel's 14nm has been improved over time. TSMC's 7nm will probably also be improved. Reply
