Senator Tom Cotton, a Republican from Arkansas, has expressed concerns about ChangXin Memory Technologies (CXMT), urging the Trump administration to adopt a tougher approach towards the company.
In a letter to Commerce Secretary Howard Lutnick, Cotton described CXMT as a significant threat to U.S. economic and military interests, emphasizing the need to prevent the company from expanding its influence in the global market.
CXMT is currently the fourth-largest producer of DRAM, a critical component in computers and smartphones, and has recently increased its market share from 4% to 10% within a year.
The senator is requesting that CXMT be added to the Bureau of Industry and Security Entity List, which would severely limit U.S. firms' ability to conduct business with the company and restrict its access to American technology.
Experts, including Kyle Chan from the Brookings Institution, noted that being on this list would prevent U.S. companies from purchasing CXMT's products, which could hinder the company's growth in the high-bandwidth memory (HBM) sector, a key area for AI development.
Despite CXMT's recent public offering and its ambitions in HBM production, its current yield rates are low, indicating production challenges. The Pentagon has already identified CXMT as having military ties, but the existing restrictions are not as stringent as those that would come from being placed on the Entity List.
Cotton's letter highlights the urgency of addressing CXMT's advancements in chip technology, which he argues could undermine American competitiveness in the semiconductor industry
