- Lead. Apple is testing memory chips from Chinese manufacturer Changxin Memory Technologies — known as CXMT — for use in iPhones and MacBooks, according to a report published by Semafor on August 9, 2026, in a move that has drawn immediate bipartisan pushback from US senators.
- Fact. A group of senators wrote to Apple in July warning against sourcing Chinese DRAM, and Apple is now proactively seeking White House clearance before proceeding — a contrast to its earlier handling of Chinese chip supplier YMTC, which ended in a regulatory confrontation.
- Stake. The episode illustrates the mounting tension between the AI-driven demand surge for high-bandwidth memory and Washington’s effort to limit Chinese semiconductor companies’ access to advanced customers and revenue streams.
Apple has begun evaluating DRAM from China’s fastest-growing memory manufacturer, Changxin Memory Technologies, for potential use in a range of its devices including iPhones and MacBooks, according to Semafor, which cited sources familiar with the company’s supply chain discussions. The Wall Street Journal separately confirmed that Apple had held early conversations with CXMT about supplying memory for devices sold in China. Apple has not commented publicly on the reports.
What Is Driving the Exploration
The primary driver is a global shortage of high-bandwidth DRAM, where demand from artificial intelligence workloads has outpaced the capacity additions that Samsung, SK Hynix, and Micron can deploy in the near term. Apple’s recent product lineup has reflected elevated component costs, with memory identified internally as a significant contributor. CEO Tim Cook cited chip costs when announcing price increases roughly two months ago. CXMT has emerged as the world’s fastest-growing DRAM supplier: in the first quarter of 2026, the Hefei-based company reported revenue of 50.8 billion yuan ($7.4 billion), a 719 percent increase year on year, and its debut on Shanghai’s STAR Market in late July produced a 466 percent first-day stock surge that made it briefly the most valuable company listed in mainland China.
Despite those growth figures, analysts note significant limitations. CXMT is estimated to be roughly two to three technology generations behind the leading memory manufacturers, and the company quoted Apple prices comparable to — or in some cases higher than — Samsung and SK Hynix, meaning Apple is unlikely to achieve the cost savings that would make any procurement decision straightforward. The evaluation is understood to be focused on devices sold within China as a localisation strategy rather than a global supply pivot.
The Political Obstacle
The national security dimension is considerable. In July, a bipartisan group of US senators wrote directly to Apple urging it not to source memory chips from CXMT, describing Chinese semiconductor companies as potential vectors for espionage and arguing that any revenue Apple sends to CXMT helps fund a competitor that the US government has sought to contain through export controls on advanced chipmaking equipment.
Apple’s response — seeking White House clearance before moving ahead — reflects a lesson absorbed from its experience with Chinese flash memory maker YMTC. In 2022, Apple announced plans to use YMTC chips in iPhones sold in China, only for the Biden administration to place YMTC on the Entity List, effectively forcing Apple to abandon the plan. The company appears to be trying to get ahead of any regulatory action this time by engaging with officials rather than presenting Washington with a fait accompli.
Washington has recently moved to restrict a range of Chinese hardware products on national security grounds, and CXMT sits in a similar grey zone: technically not yet under direct export control restrictions for the highest-end DRAM, but politically exposed as US-China technology competition intensifies ahead of a potential Xi-Trump summit in September.
What Happens Next
The outcome of Apple’s White House consultations will matter for the broader industry. If Apple secures clearance to test and eventually procure CXMT chips — even for a limited China market — it would represent a meaningful crack in the US technology containment strategy, giving CXMT revenue, manufacturing scale, and a prestigious customer reference. If the administration objects, the episode confirms that memory chips are now firmly inside the perimeter of US-China technology controls, regardless of whether they currently appear on any formal restricted list. Either outcome will be watched closely by other major technology companies assessing their own exposure to Chinese semiconductor supply chains.
