- DRAM can be used in high-demand AI memory.

## Summary

Senator Tom Cotton has urged Commerce Secretary Howard Lutnick to add Chinese chipmaker ChangXin Memory Technologies (CXMT) to the US government’s Entity List. That move would sharply restrict US firms’ ability to do business with CXMT and limit the company’s access to US technology; Cotton says the company poses a growing economic and military risk.

CXMT is the world’s fourth-largest producer of DRAM, a standard type of memory used in computers and smartphones. DRAM can also be used to make high-bandwidth memory (HBM), which is in strong demand for AI chips made by Nvidia, Google and Amazon Web Services. Samsung, SK Hynix and Micron are the three main HBM producers.
