For practitioners, chip sourcing choices highlight how AI-driven demand for high-bandwidth memory compresses supply for consumer DRAM, forcing device makers to consider geopolitically sensitive suppliers. The Financial Times reports that **Apple** has begun testing DRAM chips from Chinese state-backed **ChangXin Memory Technologies (CXMT)** for devices sold in China and is leading a lobbying effort in Washington to permit broader commercial use, citing people familiar with the matter. Reporting by **CNBC** and **MacRumors** echoes the FT coverage. The FT and other public reporting note that **CXMT** is on a U.S. military blacklist and accounts for roughly **11%** of global DRAM wafer capacity, a figure the FT says could rise to **15%** within two years, citing SemiAnalysis. Price pressure on conventional DRAM is reported to have pushed component costs up by **50-60%**, according to one outlet.
