Apple Tests CXMT DRAM as AI Boom Tightens Memory Supply

A surge in artificial-intelligence data-center construction is absorbing advanced memory-chip capacity, driving up prices and increasing cost pressure across the consumer-electronics industry. Apple is seeking access to lower-cost memory from China’s ChangXin Memory Technologies, or CXMT. The proposal has become a sensitive test for the White House, pitting its efforts to contain consumer prices against US restrictions intended to protect semiconductor supply chains and limit China’s technological advance.

Apple has recently lobbied the White House to permit purchases from CXMT, drawing fierce opposition from Micron Technology. The US memory-chip maker warned that allowing Chinese supply could weaken America’s semiconductor manufacturing base, while a bipartisan group of lawmakers has also pressed Apple to abandon the plan. As of July 31, 2026, the reports cited no proposed purchase value or firm decision date, leaving the administration to weigh near-term price relief against its broader China chip policy.

The global DRAM market is dominated by Samsung Electronics, SK Hynix and Micron, and Apple has long sourced memory from all three suppliers. China’s ChangXin Memory Technologies, or CXMT, is a major DRAM producer. Its entry into Apple’s supply chain could reshape pricing negotiations while raising questions about US-China technology controls and supply-chain security.

A new report said Apple is testing CXMT DRAM and consulting with the Trump administration to assess the political risks of purchasing the chips. Analysts said the move was intended to push down contract prices from Samsung, SK Hynix and Micron. The report did not disclose the testing date, purchase value or volume. CXMT is also accelerating development of bonded DRAM technology for AI servers.

The expansion of AI data centers is driving demand for high-bandwidth memory, prompting Samsung, SK hynix and Micron to shift capacity toward higher-margin products. Counterpoint Research data show conventional DRAM prices have quadrupled over the past three quarters. Unless Apple can increase local sourcing in China, it risks losing further market share there as it competes with Huawei's in-house chips.

The Financial Times reported on June 27 that Apple had spent more than a month lobbying the U.S. Commerce Department and the White House for approval to use DRAM from ChangXin Memory Technologies, or CXMT, which is on the Defense Department's Section 1260H list. Tim Cook also raised the matter with Treasury Secretary Scott Bessent. No procurement decision has been finalized. Apple raised prices for products including Macs and iPads by $100 to $500 on June 25.

Apple has long leveraged its vast purchasing scale to secure lower prices and stable supplies from Samsung, SK hynix and Micron. But major cloud providers are expanding AI data centers, leaving high-bandwidth memory and conventional DRAM competing for production capacity. Supply-chain leverage is gradually shifting toward AI customers.

NVIDIA’s rollout of its next-generation Rubin platform in 2026 is further boosting data-center memory demand, pushing up DRAM prices as supplies tighten. Suppliers now favor allocating limited capacity to higher-margin AI orders. Apple’s risk has shifted from rising procurement costs to potentially being unable to obtain enough chips for products including the iPhone and Mac.
