驳斥媒体误导，指出中美存储禁令不影响美光等巨头AI业务。

涉及标的： $MU

中文翻译

在《日经亚洲》新文章发布后，围绕 $MU、SK海力士和存储芯片领域出现了大量虚假信息。我预料到会发生这种情况，因为这篇文章写得极差且具有误导性，而存储行业其实非常微妙。这对美光和美光以及SK海力士几乎没有实质性影响。长鑫存储(CXMT)和中微半导体(YMTC)已被美国政府列入黑名单，无法进入中国以外的供应链。这纯属国内事务，文章却写成耸人听闻的抨击之作。例如：“中国两大主要存储制造商将全球供应短缺视为机遇……” YMTC被全面禁止（美国实体清单）——国防部1260H条款名单（中国军事公司）。CXMT也在国防部1260H名单中，属于军事关联名单。美国商务部很可能对该企业实施更多出口管制。最大的影响其实是对南亚+Nanya和旺达+Winbond这类“填补空白”的传统存储公司，这才是文章应聚焦的重点。但文章和那些想寻找逢低买入机会的人为了点击量，通过引入美光等公司散布虚假信息。细微差别在于：美光、SK海力士和三星已基本清除了来自中国的市场需求（例如美光约10%，SK海力士约15-18%），并将DRAM产能转向HBM3e和HBM4。只有三星因其在移动/消费设备领域的份额受到轻微影响。这对超大规模AI存储交易没有任何影响。

英文原文

There's a lot of disinformation around $MU, SK Hynix, and Memory after the new Nikkei Asia piece. Expected this to happen, since this is so badly written and misleading when the memory industry is so nuanced. This has close to 0 material impact on Micron and Sk Hynix. CXMT and YMTC are blacklisted by US government and supply chains outside of China. This is domestic only and is written as a sensational hit piece. eg. "China’s two major memory manufacturers view the global supply shortage as an opportunity..." YMTC is fully banned (US Entity List) - DoD Section 1260H list (Chinese Military Companies) CXMT - DoD Section 1260H list. Military-linked list. The U.S. Commerce Department is likely to slap more export controls on this firm. The biggest impact it would have is on "legacy fill in the void" type companies like Nanya + Winbond, which should have been the focus. But the article and people who want a dip-buying opportunity decided to clickbait/spread disinformation by throwing in Micron and others for views. Naunce is Micron, Sk Hynix, and Samsung have largely hollowed out their demand from China (eg. ~10% micron, ~15-18% Sk hynix), and shifted dram capacity to hbm3e and hbm4. Only Samsung is slightly affected given their share with mobile/consumer devices. There is no effect on the hyperscaler AI memory trade.
