中国DRAM专家CXMT瞄准进入NAND闪存领域

NAND闪存市场可能迎来一个新玩家，而且来自中国。长鑫存储技术有限公司（CXMT）已经搅动了DRAM市场，据报正准备进入NAND闪存，以利用AI服务器需求激增所驱动的全球存储短缺。数据中心需要更多基于NAND闪存的固态硬盘（SSD）来存储AI工作负载。

据路透社报道，该公司正在其北京新晶圆厂建设一条NAND芯片研发产线。此外，CXMT已在北京设立一家研究院，项目包括NAND闪存技术的开发。路透社还引用了一家未具名中国初创公司的话称，该公司目前正与CXMT洽谈，拟在其面向AI系统和超级计算机的存储产品中使用CXMT的NAND芯片。

首先，这一点值得注意，因为CXMT正在超越其核心DRAM业务。中国的两大存储明星CXMT和长江存储科技有限责任公司（YMTC）迄今在两大主要存储细分领域战略性地运营：CXMT是中国最大的DRAM制造商，YMTC则在中国NAND市场领先。

然而，今年4月，路透社报道称，YMTC已向客户发送低功耗DRAM样品，同时权衡进入CXMT的核心市场。YMTC预计在2026年底前获得客户反馈，这将帮助其决定是否开始DRAM生产。如今CXMT正在考虑进军NAND闪存市场。

表面上看，CXMT和YMTC似乎准备进入彼此的存储地盘。然而，CXMT和YMTC都得到中国国家半导体基金和地方政府的支持。CXMT在中国东部安徽省省会合肥的支持下成长；YMTC在中国中部湖北省省会武汉的支持下扩张。

闪存的机遇窗口

更仔细地观察CXMT和YMTC侵入彼此存储领域，会发现这不仅仅是在中国国内市场引发直接竞争。CXMT进入NAND可能不可避免地会在国内设备分配、洁净室工具配额以及来自区域机构的专业工程人才方面产生摩擦。然而，这也消除了中国存储消费者的单一供应商脆弱性。

存储行业领导者三星和SK海力士在DRAM和NAND市场均保持主导地位，美光随后跟进，尽管其最初在NAND闪存方面落后。双存储组合使三星等芯片制造商能够通过在DRAM和NAND业务之间持续转移资本来吸收市场低迷。

CXMT和YMTC很可能都想成为DRAM和NAND的一站式供应商，就像其更大的竞争对手美光、三星和SK海力士一样。时机再好不过，因为AI服务器需求驱动的全球存储短缺，行业高管预计至少持续到2027年。

在存储供应持续紧张的情况下，CXMT和YMTC都可能通过激进的价格竞争获得全球市场份额。然而，据韩国报纸《朝鲜日报》称，这代表的是对全球竞争对手的长期竞争威胁，而非即时的供应响应。

在存储三巨头——美光、三星和SK海力士——将资本支出优先投向DRAM和高带宽内存（HBM），限制NAND闪存产能增加并加剧该细分领域短缺之际，这为中国最大的存储芯片制造商提供了一个机遇窗口。

但问题是：这一举措可行性如何？CXMT既未宣布完整的商业产能目标，也未公开详细的生产时间表。

CXMT能成功吗？

显然，CXMT的NAND计划仍在进行中。NAND闪存是半导体行业资本最密集的领域之一。它需要独特的工具配置和化学品供应链，以及与DRAM完全不同的专利架构。

NAND制造需要专门的工艺技术、生产设备、质量控制以及长期设计验证。因此，从研发线转向具有商业竞争力的量产将涉及重大的技术和财务挑战。

尽管该公司在重磅IPO后资金充裕，但在美国出口管制下，获取先进芯片制造工具仍构成重大挑战。在技术方面，从DRAM制造转向垂直3D NAND制造带来了严峻的运营挑战。DRAM依赖精确的横向光刻在微小尺寸上图案化密集电容器网络，而3D NAND器件则是垂直制造的。

因此，过去十年致力于开发有竞争力DRAM技术的CXMT，很可能将在下一个十年扩展到DRAM之外并进入NAND闪存领域。这一向闪存的战略扩张也标志着中国大陆在关键供应链中巩固半导体自给自足更广泛运动的一个转折点。

The NAND flash market is likely to have a new player, and it’s from China. ChangXin Memory Technologies (CXMT), which has already shaken up the DRAM market, is reportedly preparing to enter NAND flash to capitalize on a global memory shortage driven by surging demand from AI servers. Data centers need more solid-state drives (SSDs)—built around NAND flash—to store AI workloads.

According to Reuters, the company is setting up an R&D production line for NAND chips at its new fab in Beijing. Moreover, CXMT has established a research institute in Beijing, where projects include the development of NAND flash technology. Reuters also quoted an unnamed startup in China that is currently in talks with CXMT to use its NAND chips in storage products for AI systems and supercomputers.

First and foremost, it’s noteworthy because CXMT is moving beyond its core DRAM business. China’s twin memory stars, CXMT and Yangtze Memory Technologies Corp. (YMTC), have so far operated strategically in two major memory segments: CXMT is China’s largest DRAM manufacturer, and YMTC leads the NAND market in China.

However, in April this year, Reuters reported that YMTC had sent low-power DRAM samples to customers as it weighed entry into CXMT’s core market. YMTC expects customer feedback by the end of 2026, which will help it decide whether to start DRAM production. Now CXMT is considering a foray into the NAND flash market.

On the surface, it may seem that CXMT and YMTC are readying to move into each other’s memory turf. However, both CXMT and YMTC are backed by China’s national semiconductor fund and local governments. CXMT grew with ⁠backing from Hefei, the provincial capital of Anhui province in eastern China; YMTC expanded with backing from Wuhan, the provincial capital of central Hubei province.

A flash window of opportunity

A closer look at CXMT and YMTC encroaching on each other’s memory territories shows it’s about more than sparking direct competition in China’s domestic market. CXMT’s entry into NAND could inevitably generate friction over domestic equipment distribution, cleanroom tooling quotas, and specialized engineering talent from regional institutions. However, it also eliminates single-supplier vulnerabilities for memory consumers in China.

Memory industry leaders Samsung and SK Hynix have maintained commanding positions across both DRAM and NAND markets, and Micron has followed suit, though it initially lagged in NAND flash. The dual-memory portfolio allows chipmakers such as Samsung to absorb market downturns by continuously shifting capital between DRAM and NAND operations.

Both CXMT and YMTC likely want to become one-stop shops for DRAM and NAND, just like their bigger rivals Micron, Samsung, and SK Hynix. The timing couldn’t be better, amid a global memory shortage driven by AI server demand that industry executives expect to persist through at least 2027.

Both CXMT and YMTC could gain global market share by competing aggressively on price as memory supplies remain tight. However, according to the Korean newspaper Chosun Ilbo, that represents a longer-term competitive threat for global rivals rather than an immediate supply response.

At a time when the memory troika—Micron, Samsung, and SK Hynix—has prioritized capital spending on DRAM and high-bandwidth memory (HBM), limiting additions to NAND flash capacity and worsening shortages in this segment mark a window of opportunity for China’s largest memory chipmaker.

But the question is: How viable is this move? CXMT has neither announced a full commercial capacity target nor a publicly detailed production timetable.

Can CXMT pull it off?

Apparently, CXMT’s NAND plan is a work in progress. NAND flash is among the most capital-intensive undertakings in the semiconductor industry. It requires distinct tooling configurations and chemical supply chains, as well as completely different patent architectures compared to DRAM.

NAND manufacturing entails specialized process technology, production equipment, quality controls, and long-term design validation. Therefore, moving from an R&D line to commercially competitive volume production would involve substantial technical and financial challenges.

While the company is awash in cash after a blockbuster IPO, access to advanced chipmaking tools still poses significant challenges amid U.S. export controls. On the technical front, the shift from DRAM fabrication to vertical 3D NAND manufacturing creates steep operational challenges. DRAM relies on precise lateral photolithography to pattern dense capacitor networks at tiny dimensions, while 3D NAND devices are manufactured vertically.

So, CXMT, which spent the past decade developing a competitive DRAM technology, will most likely spend the next decade expanding beyond DRAM and into the NAND flash realm. This strategic expansion into flash memory also marks an inflection point in mainland China’s broader campaign to solidify semiconductor self-reliance across critical supply chains.
