Apple tests CXMT memory chips for China-bound iPhones and MacBooks amid AI-driven DRAM squeeze

Apple is seeking White House approval to use off-the-shelf CXMT chips in China-sold devices as lawmakers object and CXMT's HBM push challenges Samsung Electronics and SK Hynix.

Fact Check
The WSJ article ('Apple Tests Chinese Memory Chips as Supply Squeeze Bites') directly confirms every element of the claim: Apple tested CXMT memory chips across iPhones and MacBooks, held early talks to source components for devices sold in China, is seeking White House approval, and this is driven by an AI-driven memory crunch. Reuters ('Apple seeks approval to buy chips from blacklisted Chinese company, FT reports'), citing the FT, independently corroborates that Apple is lobbying the White House/administration to buy CXMT memory chips amid AI-driven memory price pressures. Multiple credible outlets align, giving high confidence.

Summary

Apple has been testing memory chips from China's CXMT for iPhones and MacBooks sold in China as it looks to ease shortages and rising costs tied to the artificial-intelligence buildout that has tightened the DRAM market. The Wall Street Journal said Apple is seeking White House approval to use off-the-shelf CXMT chips because U.S. export controls imposed under President Donald Trump's administration bar American companies from sharing technical information with the Chinese supplier, while six senators from both parties have asked Apple to pledge by August 21 that it will not use chips from CXMT or Yangtze Memory Technologies. The report also points to a broader competitive threat to Samsung Electronics and SK Hynix as CXMT expands DDR5 and LPDDR5X production, allocates 20% of its DRAM wafers to HBM3, targets HBM3E mass production by 2027 and bolsters its firepower after a 57.9 billion yuan IPO and a 460% first-day jump on Shanghai's STAR Market.
