Apple is evaluating memory chips from ChangXin Memory Technologies (CXMT) for use in iPhones and MacBooks sold in China. The Pentagon has designated CXMT as a Chinese military company, and Apple has sought assurances from the U.S. government that the firm will not face future sanctions.

The evaluation comes as DRAM prices have surged by more than 50 percent in a single quarter in 2026. Prices have roughly quadrupled since fall 2025. Apple CEO Tim Cook announced price increases on Apple products approximately two months prior to August 2026. Cook cited surging memory and storage costs as the reason for the adjustments.

CXMT technology lags behind SK Hynix, Samsung, and Micron by roughly two to three generations. Despite this gap, CXMT memory products are priced at similar or higher levels than components from those established leaders. Much of CXMT's current output goes to Chinese customers such as ByteDance, Tencent, and Xiaomi. The company has reached about 7 percent of global DRAM revenue and reported triple-digit year-over-year revenue growth.

Dell and HP are also evaluating memory chips from CXMT. Acer is sourcing CXMT chips for products destined for markets beyond the United States. These moves occur as worldwide PC shipments declined 4 percent year-on-year in the second quarter of 2026. Worldwide smartphone shipments fell 11 percent year-on-year in the same period.

A bipartisan group of lawmakers sent a letter to the Commerce Department on July 14 demanding CXMT be added to the Entity List. The Entity List is an export-control designation that imposes licensing requirements on specified transactions. A bipartisan group of U.S. senators wrote to Apple in July urging the company not to pursue Chinese chips. U.S. export controls prevent American companies from transferring certain technologies to CXMT.

Hefei, the capital of Anhui province, funded CXMT after private investors declined. The Chinese government established Fujian Jinhua and CXMT, then known as Innotron Memory, as DRAM ventures. This development followed the creation of a national integrated circuit plan by the Chinese government in 2014. A Chinese state-backed group attempted to buy Micron for $23 billion in 2015.

Samsung, SK Hynix, and Micron hold more than 90 percent of the DRAM market. Ten DRAM suppliers held roughly 80 percent of the market in 1995. Hitachi, IBM, LG Electronics, Mitsubishi Electric, NEC, and Texas Instruments have exited the DRAM market.

Qimonda liquidated after receiving multiple bailout packages from the German government. Elpida collapsed less than three years after Japan infused ¥30 billion of public money into the company.

Google, Microsoft, Meta, and Amazon have expanded capital expenditure budgets for AI infrastructure. CXMT has allocated its available production capacity for 2026. The company plans further capacity expansion through 2028.

Apple invested $55 billion a year in its Chinese supply chain by 2015. The company has trained 28 million workers in China.

Apple migrated its mainland iCloud data and encryption keys to a Chinese state-owned operator in 2018. The company limited open AirDrop sharing in China to a ten-minute window in 2022. Chinese government agencies restricted iPhone use in 2023.

Apple removed Western messaging applications from its domestic app store in China in 2024 following a regulator order. Foxconn recalled hundreds of Chinese engineers from its Indian facilities during reported directives from Chinese officials to curb equipment and technology transfers to India.

What's New

Additional reporting indicates Apple is evaluating CXMT memory chips for iPhones and MacBooks. The company has held preliminary discussions with CXMT about sourcing memory components for devices sold in China. CXMT memory products are priced at similar or higher levels than components from Micron, SK Hynix, and Samsung. CXMT technology lags behind SK Hynix, Samsung, and Micron by roughly two to three generations.

Much of CXMT's current output goes to Chinese customers such as ByteDance, Tencent, and Xiaomi. Apple CEO Tim Cook announced price increases on Apple products approximately two months prior to August 2026. Cook said the company needs memory pricing and supply to return to reasonable levels for consumer products. Research titled NSIM-ACE: An Interconnection Network Simulator for Evaluating Remote Direct Memory Access was published in 2016 in Proceedings of the 6th International Conference on Simulation and Modeling Methodologies, Technologies and Applications.

Why It Matters

The evaluation of CXMT chips by major technology firms occurs within a concentrated global market where Samsung, SK Hynix, and Micron hold more than 90 percent of DRAM share. CXMT has reached about 7 percent of global DRAM revenue and reported triple-digit year-over-year revenue growth, signaling its emergence as a competitor despite technological gaps. The Pentagon's designation of CXMT as a Chinese military company introduces national security considerations into commercial supply chain decisions.

Political pressure has intensified, with a bipartisan group of lawmakers sending a letter to the Commerce Department on July 14 demanding CXMT be added to the Entity List. U.S. export controls currently prevent American companies from transferring certain technologies to CXMT. Apple's request for assurances that CXMT will not face future sanctions shows the tension between cost mitigation strategies and regulatory compliance. The outcome may influence how other manufacturers balance supply needs against geopolitical risks.
