Apple is testing memory chips made by China’s ChangXin Memory Technologies, known as CXMT, as a global supply squeeze raises costs and complicates the production plans of consumer-electronics companies.

The work is an early technical evaluation, not a commitment to use the chips in commercial products.

The company has held preliminary discussions with CXMT, China’s largest maker of DRAM, the short-term memory used in smartphones, computers and other electronic devices while they are running.

Apple is considering the supplier as it seeks to widen its options for iPhones, iPads and Mac computers, with any initial use expected to be focused on devices sold in China.

The immediate pressure comes from the artificial-intelligence boom.

Major chipmakers have shifted capacity and investment towards high-performance memory for AI data centres, leaving consumer-device makers to compete for a tighter supply of conventional memory.

Prices have risen, and manufacturers across the computer industry have been testing Chinese suppliers to reduce their dependence on Samsung Electronics, SK Hynix and Micron Technology.

For Apple, qualifying CXMT’s components could provide an additional source of supply, but it would not remove the wider shortage.

A supplier must meet demanding standards on performance, power use, heat management, reliability and production consistency before its chips can be incorporated into a high-volume Apple device.

The potential relationship is politically sensitive.

CXMT appears on a United States Defence Department list of Chinese companies identified as having links to the country’s military-industrial system.

That designation does not automatically bar private American companies from buying its products, but it creates a risk that any Apple deal could draw opposition from lawmakers or be affected by future trade restrictions.

Apple has previously faced political pressure over efforts to source components from Chinese chipmakers.

Its discussions with CXMT therefore sit at the intersection of two competing priorities: securing enough memory for consumer devices and avoiding a move that could deepen tensions between Washington and Beijing.

No supply agreement has been announced, and Apple has not confirmed that CXMT chips will appear in any future product.

The next test is whether the company completes technical qualification and receives sufficient political assurance to turn preliminary talks into a commercial arrangement.
