Chinese Memory Maker CXMT Sues Pentagon to Get Off US List
CXMT says its designation as a Chinese military company has cost it reputation and business, in a market where memory prices have quadrupled and the bloc imports every chip it uses.
Background
CXMT showcased the DDR5 & LPDDR5X at the 22nd China International Semiconductor Expo (IC China) on November 23, 2025.
Lawsuit Details
CXMT has sued the US Department of Defense in Washington seeking removal from the list identifying it as a Chinese military company, a designation that blocks defence contracts without restricting commercial sales. The company is the world’s fourth-largest DRAM maker and passed Tencent (164news.com on tencent) this month to become China’s most valuable listed company.
"CXMT is not a military company and has no affiliation with the Chinese military," the Hefei chipmaker said in a statement. It says it designs chips for civilian and commercial use.
The designation, first made in January 2025, has been a source of contention, with the company briefly removed in February only to be put back on in June.
Impact and Implications
The designation does not stop anyone from buying from CXMT. However, it carries risks, as it is widely read as a step towards the Entity List, which does restrict trade, and serves as a red flag to investors.
Europe, with no volume DRAM manufacturing, is particularly vulnerable to these price increases and supply chain disruptions. Every memory chip in a European product is imported, often from CXMT, with American controls influencing European supply chains.
Conclusion
The lawsuit highlights the complex interplay between American lists, Chinese memory makers, and European reliance on imported chips. It raises questions about the consequences of American controls on European manufacturers and the lack of European rules to mitigate these risks.
