Apple said to be testing CXMT memory chips as AI demand tightens supply

Apple is testing memory chips made by Chinese producer ChangXin Memory Technologies, according to reports, as AI infrastructure buildouts absorb global memory output and tighten supply for other buyers. Qualifying an additional supplier would broaden Apple's sourcing options in a market where pricing has moved sharply higher. Separately, a senior Republican lawmaker urged the US to block any advanced chips from reaching sanctioned Chinese firms, underlining the political sensitivity of US-China semiconductor supply links.
