Apple Begins Testing Controversial Chinese Memory Chips
Apple has reportedly started testing memory chips from Chinese supplier CXMT, despite U.S. national security concerns over potential ties to the Chinese military. The company is evaluating CXMT's LPDDR5 memory chips for possible use in iPhones and other devices, which could reduce reliance on Samsung and SK Hynix but faces regulatory hurdles.
Background
Apple is reportedly testing NAND flash memory chips from YMTC (Yangtze Memory Technologies Corp), a leading Chinese semiconductor company. YMTC has been blacklisted by the U.S. Commerce Department since late 2022, meaning American companies are restricted from selling it advanced equipment or technology. If Apple adopts YMTC's chips, it would be a major win for Chinese tech, potentially weakening US export controls designed to slow China's semiconductor advances. However, it would also risk backlash from US lawmakers and national security hawks, especially given Apple's heavy reliance on the Chinese market (roughly 20% of its revenue) and ongoing tensions over supply chain security. The move echoes Apple's earlier diversification away from total dependence on Samsung and SK Hynix for memory, but using a sanctioned supplier is a new, higher-stakes step.
