Apple is testing memory chips from China’s CXMT for use in iPhones and MacBooks, according to a report by The Wall Street Journal cited by multiple outlets. The testing indicates Apple is evaluating alternative supply options for a key component—dynamic and related memory used across devices.

The coverage links the effort to broader strain in the memory chip market, which is being pressured by demand growth tied to the AI boom. Several reports describe the move as part of Apple’s response to supply constraints and efforts to ease the availability of components used in consumer electronics.

While all sources point to the same WSJ reporting and the same general purpose—mitigating a memory supply crunch—the outlets mainly differ in emphasis rather than in core facts. Some focus on the specific supplier (CXMT) and device targets (iPhones and MacBooks), while others underscore that the wider market context is driven by AI-related memory demand.
