Senator Urges US to Blacklist Chinese Chipmaker CXMT
Tom Cotton asks Howard Lutnick to restrict the memory chip manufacturer to protect national security and technological dominance.
Senator Tom Cotton has sent a letter to Commerce Secretary Howard Lutnick requesting a ban on ChangXin Memory Technologies. The lawmaker argues that the Chinese company poses a growing threat to the economic prosperity and military superiority of the United States.
CXMT currently ranks fourth globally in DRAM production, which is a vital component for computers and smartphones. The request seeks to add the company to the Commerce Department entity list, which would severely restrict its access to American technology.
The primary concern involves the expansion of CXMT into the high-bandwidth memory market, known as HBM. These components are essential for the operation of artificial intelligence chips developed by industry giants.
Currently, HBM production is concentrated among three global firms. CXMT’s share of the DRAM market jumped from 4% to 10% in just one year, highlighting its rapid growth in the semiconductor sector.
Although the company's HBM capabilities are still in the early stages, the Chinese advance is raising alarms regarding the global supply chain. The restriction would prevent American firms from doing business with the manufacturer and limit its international reach.
