In a letter addressed to Apple CEO Tim Cook, the senators asked the company not to use memory chips from the two Chinese suppliers, even in devices intended exclusively for the Chinese market. The senators argued that even if Chinese memory chips were initially limited to products sold in China, they could eventually be deployed globally through procurement decisions. They also questioned whether sourcing from Chinese suppliers would significantly lower costs, citing analysis that CXMT's pricing is sometimes higher than competing products. Moreover, the letter asked Apple to commit by August 21 that it will not incorporate CXMT or YMTC memory chips into its products. However, reports claim that Apple did not respond to the lawmakers' letter immediately.
