Apple tests Chinese CXMT DRAM chips for China devices

Apple has begun testing DRAM memory chips from the Chinese state-backed manufacturer ChangXin Memory Technologies (CXMT) for use in devices sold within China, according to a report. The move, which follows Apple's earlier request for U.S. government approval to work with the chipmaker, signals a significant potential shift in the tech giant's supply chain amid global memory shortages and rising costs.

The testing is currently limited to devices intended for the Chinese market. While Apple has not finalized a commercial deal, the evaluation of CXMT's chips represents a major step toward diversifying its suppliers beyond its current primary partners: Samsung Electronics, SK Hynix, and Micron Technology. Apple reportedly approached U.S. officials in late May or early June to seek permission for the potential partnership and has been lobbying the administration since.

CXMT's inclusion in these tests highlights its rapid ascent. Once a relatively unknown firm, it has become the world's fourth-largest producer of DRAM chips, with its global production capacity share reaching approximately 11% last year. Analysts project that figure could rise to around 15% by 2028 as the company...
