原文深度解读
本文报道了中国NAND闪存厂商长江存储(YMTC)正推进在上海科创板IPO的进程,以利用AI时代存储芯片短缺的机遇并提升全球地位。文章涉及YMTC与DRAM厂商长鑫存储(CXMT)的对比、YMTC的市场份额、技术进展(267层3D NAND)、面临的挑战(美国实体清单、产品结构偏向消费级)以及国内外市场平衡问题。关键数字包括:CXMT IPO募资近100亿美元、YMTC 2026年第二季度全球NAND闪存出货量份额14%、企业级SSD占全球NAND比特出货量48%等。
- YMTC是中国NAND闪存专业厂商,与DRAM厂商CXMT并称“双长”,CXMT于上月完成IPO募资近100亿美元,YMTC已开始正式IPO准备,拟在科创板上市,并已完成上市前辅导。
- YMTC成立于2016年7月,位于湖北武汉,是中国唯一的NAND闪存芯片制造商,目前是全球第三大NAND闪存供应商,仅次于三星和SK海力士。
- 根据Counterpoint Research数据,YMTC在2026年第二季度占全球NAND闪存出货量的14%,超过铠侠、美光和闪迪。
- YMTC已开始量产基于其专有Xtacking 4.0架构的267层3D NAND芯片,并正在开发超过300层的NAND闪存。
- YMTC的NAND闪存出货量在2026年第二季度首次超过日本铠侠,但在NAND闪存收入方面仍排名第五,落后于铠侠和美光,因为出货更多比特并不自动意味着赚更多钱。
- YMTC自2022年起被列入美国商务部实体清单,这使其难以获得最先进的光刻工具;同时其NAND产品组合主要集中在消费应用,企业级SSD占比有限,而企业级SSD在2026年第二季度占全球NAND比特出货量的48%,几乎是一年前26%的两倍。
供应链影响
- YMTC的IPO可能为其扩大产能和研发提供资金,但受实体清单限制,其先进设备获取可能受限,产能扩张速度可能取决于国产设备替代进展。
- YMTC计划在2026年下半年提高企业级SSD在其NAND闪存产品组合中的占比,这可能影响全球企业级SSD市场的供应格局,具体取决于其产品良率和客户接受度。
- 随着AI推理需求增长,服务器对NAND比特的消耗预计将超过一半,YMTC的企业级SSD占比提升可能使其在数据中心存储供应链中扮演更重要角色,但可能面临来自三星、SK海力士、美光等现有供应商的竞争。
- YMTC和CXMT的IPO可能加剧中国存储芯片自给自足的进程,可能影响全球存储芯片市场的供需平衡,但具体影响取决于其产能爬坡速度和全球需求变化。
- YMTC的出货量份额超过收入份额,表明其产品单价较低,未来可能通过提升企业级SSD占比来改善收入结构,这可能影响其定价策略和供应链议价能力。
系统解读,仅作为判断线索,不构成备货、出货、涨价或投资建议。
长江存储科技有限责任公司(YMTC),中国双存储明星之一,与长鑫存储(CXMT)并称,正跟随CXMT的IPO路径,以利用AI时代的存储芯片短缺,并在全球存储精英中战略定位。与专注于DRAM和高带宽存储器(HBM)的CXMT不同,YMTC专注于NAND闪存设备。
CXMT和YMTC常被称为中国快速崛起的半导体市场中的“双长”。在CXMT上月成功IPO募资近100亿美元后,YMTC已开始正式IPO准备,拟在上海科创板上市。它已完成上市前辅导,这使其距离在中国A股市场上市更近一步。
YMTC于2016年7月在湖北省武汉市成立,是中国唯一的NAND闪存芯片制造商,目前是全球第三大NAND闪存供应商,仅次于三星和SK海力士。根据Counterpoint Research的数据,YMTC在2026年第二季度占全球NAND闪存出货量的14%,超过铠侠、美光和闪迪。
Counterpoint还报告称,YMTC已开始量产基于其专有Xtacking 4.0架构的267层3D NAND芯片。这不仅仅是层数上的成就;它反映了架构和工艺控制方面的进步。此外,YMTC目前正在开发超过300层的NAND闪存。

AI时代的NAND闪存
值得注意的是,YMTC的NAND闪存出货量在今年第二季度首次超过日本铠侠。然而,YMTC在NAND闪存收入方面仍排名第五,落后于铠侠和美光,尽管出货比特数较少,但它们继续产生更多NAND收入。这是因为出货更多比特并不自动意味着赚更多钱。
这要求YMTC的晶圆厂配备更精密的制造设备,而IPO筹集的资金将不可避免地帮助它在这方面加大投入。然而,与CXMT一样,自2022年以来,它一直被列入美国商务部的实体清单,这使得YMTC更难获得最先进的光刻工具。

YMTC面临的另一个挑战:虽然其NAND产品组合主要集中在消费应用,如笔记本电脑和智能手机,但它在数据中心使用的高端企业级SSD方面敞口有限。这一点至关重要,因为根据Counterpoint的数据,企业级SSD在2026年第二季度占全球NAND比特出货量的48%,几乎是一年前26%份额的两倍。
随着AI工作负载从训练转向推理,服务器预计到2026年底将消耗超过一半的NAND比特,这需要更快地访问大型数据集和键值(KV)缓存。这反过来使高容量企业存储变得越来越有价值。YMTC承认这种推理驱动的转变,并计划在2026年下半年提高企业级SSD在其NAND闪存组合中的占比。
国内还是全球?
YMTC及其DRAM同行CXMT多年来依赖政府资金并累积亏损。因此,中国当局期望这些半导体存储公司优先向国内OEM和ODM供应。然而,与此同时,YMTC和CXMT被视为中国在长期由三星、SK海力士和美光主导的全球存储芯片市场中立足的最大希望。
AI驱动的存储芯片短缺以及由此导致的飙升价格,为这些存储弱势企业加入由三星、SK海力士和美光组成的小型存储精英俱乐部打开了前所未有的机会窗口。然而,要做到这一点,YMTC和CXMT都必须筹集资金以提升其存储设计并建造更多晶圆厂以提高产能。
DRAM专家CXMT上个月通过非常成功的IPO筹集了资金,现在NAND闪存厂商YMTC正紧随其后。随着中国推动半导体存储自给自足的势头不断增强,全球AI数据中心的建设也正在将这些存储行业弱势企业转变为国际参与者。

Yangtze Memory Technologies Co. Ltd (YMTC), China’s twin memory star alongside ChangXin Memory Technologies (CXMT), is following CXMT’s IPO path to capitalize on the memory chip crunch in the AI era and strategically position itself among the global memory elite. Unlike CXMT, which specializes in DRAM and high-bandwidth memory (HBM), YMTC focuses on NAND flash devices.
CXMT and YMTC are often referred to as “Two Changs” of China’s rapidly emerging semiconductor market. After CXMT’s blockbuster IPO last month, which raised nearly $10 billion, YMTC has begun formal IPO preparations to list on Shanghai’s STAR market. It has completed the pre-IPO advisory process, which brings it one step closer to listing on China’s A-share market.
YMTC, founded in Wuhan in Hubei province in July 2016, is China’s sole manufacturer of NAND flash chips and currently ranks as the world’s third-largest NAND flash supplier, following Samsung and SK Hynix. According to Counterpoint Research, YMTC captured 14% of global NAND flash memory shipments in the second quarter of 2026, surpassing Kioxia, Micron, and SanDisk.
Counterpoint also reports that YMTC has started mass production of 267-layer 3D NAND chips built around its proprietary Xtacking 4.0 architecture. It’s more than a layer-count achievement; it reflects advances in architecture and process control. Moreover, YMTC is currently developing a NAND flash beyond 300 layers.

NAND flash in AI era
It’s worth noting that YMTC’s NAND flash shipments in the second quarter of this year surpassed Japan’s Kioxia for the first time. However, YMTC remained fifth in NAND flash revenue, behind both Kioxia and Micron, which continue to generate more NAND revenue despite shipping fewer bits. That’s because shipping more bits does not automatically mean earning more money.
That calls for more sophisticated manufacturing equipment at YMTC’s fabs, and capital raised from the IPO will inevitably help it up the ante on this front. However, like CXMT, it’s been on the U.S. Commerce Department’s Entity List since 2022, which makes it harder for YMTC to access the most advanced lithographic tools.

Another challenge facing YMTC: While its NAND product mix is mostly concentrated in consumer applications such as notebooks and smartphones, it has limited exposure to the expensive enterprise SSDs used in data centers. That’s critical because, according to Counterpoint, enterprise SSDs accounted for 48% of global NAND bits shipped in the second quarter of 2026, almost double the 26% share a year earlier.
Servers are expected to consume more than half of all NAND bits by the end of 2026 as AI workloads shift from training to inference, which requires faster access to large datasets and key-value (KV) caches. That, in turn, makes high-capacity enterprise storage increasingly valuable. YMTC acknowledges this inference-driven shift and plans to increase the share of enterprise SSDs in its NAND flash mix during the second half of 2026.
Domestic or global?
YMTC and its DRAM counterpart CXMT spent years relying on government funding and racking up losses. So, authorities in China expect these semiconductor memory firms to prioritize supply to domestic OEMs and ODMs. At the same time, however, YMTC and CXMT are seen as China’s best hopes for establishing a foothold in a global memory chip market long dominated by Samsung, SK Hynix, and Micron.
AI-driven memory chip shortages, and the resulting soaring prices, have opened an unprecedented window of opportunity for these memory underdogs to join the small club of memory elite made up of Samsung, SK Hynix, and Micron. To do so, however, both YMTC and CXMT must raise capital to sharpen their memory designs and build more fabs to boost production capacity.
DRAM specialist CXMT raised capital through a highly successful IPO last month, and now NAND flash player YMTC is following in its footsteps. As China’s push for semiconductor memory self sufficiency continues to gather momentum, the global buildout of AI data centers is also turning these memory industry underdogs into international players.
