Two Chinese memory makers stand ready to ease a painful shortage. Lawmakers in Washington want none of it.
Rep. John Moolenaar, a Michigan Republican, and Rep. George Whitesides, a California Democrat, sent a letter to Commerce Secretary Howard Lutnick this week. They urged the Trump administration to bar American companies from buying chips made by ChangXin Memory Technologies, known as CXMT, and Yangtze Memory Technologies Corp., or YMTC. The missive, first reported by The Register, warns that such purchases would flood markets with subsidized products. They would undermine Western producers. They would hand advantages to the Chinese military.
The timing feels urgent. Demand for memory has exploded with the rise of artificial intelligence systems. Prices have climbed sharply. PC makers such as Apple, Dell and HP have started testing cheaper options from the Chinese suppliers. Yet security hawks see danger. Short-term relief could lock in long-term dependence.
CXMT focuses on dynamic random access memory. YMTC makes NAND flash for storage. Both firms launched in the past decade. Their products historically trailed industry leaders from Micron, Samsung and SK Hynix. But the gap has narrowed. CXMT now produces chips that meet basic specs for consumer devices. Reports suggest it could reach volume output of advanced high-bandwidth memory variants soon.
A guest post on ChinaTalk from April 2025 noted CXMT had begun mass production of HBM2 in late 2024. The firm trails global leaders by three to four years. Plans call for HBM3 output in the first half of 2026. HBM3E could follow in 2027. “My best guess is China’s HBM development trails market leaders by roughly only four years,” wrote analyst Ray Wang. The progress comes despite repeated rounds of American export controls on equipment and technology.
Those controls have slowed but not stopped the advance. The Commerce Department placed YMTC on its Entity List years ago. CXMT appears on the Pentagon’s Section 1260H list of Chinese military companies. Neither designation fully prevents sales of finished chips to private buyers in the United States. That loophole worries Moolenaar and Whitesides.
“US reliance on Chinese memory producers will expose Western manufacturers to a deluge of state-subsidized Chinese memory, putting our memory manufacturing base and supply chains at risk,” they wrote in the letter obtained by the House Select Committee on the CCP. They called for an executive order or agency rule to close the gap. They also pushed to add CXMT to the Entity List and strengthen limits on YMTC.
Memory differs from processors. It follows common standards. Buyers can switch suppliers with relative ease. This commodity nature makes price the deciding factor. Chinese state support could let CXMT and YMTC undercut rivals for extended periods. Western firms might exit the market. Rebuilding capacity would take years.
The current crunch traces to several causes. AI training clusters consume enormous amounts of high-bandwidth memory. Producers have diverted output from standard DRAM and NAND to meet that demand. New fabrication plants require four years or more to reach full production. The Register reported earlier this month that shortages could linger into 2028. Prices for enterprise solid-state drives have risen accordingly.
Apple has taken notice. Executives asked the administration for guidance before committing to Chinese sources. The Financial Times detailed the outreach late last month. The company wants lower costs. It also wants regulatory certainty. Other PC vendors have begun qualifying the Chinese parts. The appeal is obvious. Relief from elevated prices could protect margins on laptops and servers.
But national security arguments carry weight in today’s Washington. Moolenaar chairs the House Select Committee on the Chinese Communist Party. He has long warned about technology transfer risks. The letter argues that purchases would subsidize military-civil fusion programs. CXMT and YMTC both maintain ties that raise flags for American officials.
Recent coverage shows the debate has intensified. A story in Yahoo Finance published yesterday highlighted Apple’s plans drawing fresh scrutiny. Shares of the company rose modestly on the news. Investors appear to weigh the cost savings against potential delays or restrictions.
Earlier this year Moolenaar sent another letter to Lutnick on related memory issues. That January 2026 note, covered by Bloomberg, focused on how shortages could limit approvals for Nvidia sales to China. The lawmaker cited concerns from Samsung, SK Hynix and Micron. The pattern is clear. Memory sits at the center of broader technology competition.
China has responded to previous controls by stockpiling and accelerating domestic efforts. Reports from late 2024 showed Huawei and others buying millions of HBM stacks before new rules took effect. Such moves buy time. They do not solve underlying gaps in advanced manufacturing tools. American limits on lithography machines and other equipment continue to bite.
Still, progress continues. CXMT aims to dedicate significant capacity to HBM3 lines next year. Domestic toolmakers in China are developing assembly equipment. A January 2026 article on Tom’s Hardware outlined these parallel tracks. If successful, the country could reduce reliance on foreign suppliers for its own AI systems.
For American buyers the choice is stark. Pay higher prices to trusted allies. Or accept risk by turning to Beijing-linked vendors. The lawmakers favor the first path. They point to expanded domestic and allied manufacturing as the lasting answer. Micron has broken ground on new facilities. South Korean giants continue to invest. But construction timelines stretch long. Relief will not arrive quickly.
So far the Trump administration has held off on fresh entity listings while talks with China continue. That pause may end. The letter from Moolenaar and Whitesides adds bipartisan pressure. Commerce officials must weigh economic pain against strategic goals. Shortages hurt consumers and businesses alike. Yet dependence on adversary supply chains carries its own costs.
Industry voices have stayed largely quiet in public. No major memory producer issued statements Thursday. Analysts expect private lobbying to intensify. PC makers want options. Chipmakers want protection. The administration sits in the middle.
And the stakes rise with each new AI model. Larger clusters demand more memory. Prices stay elevated. Chinese vendors improve their yields. The window for easy substitution may close if restrictions tighten. Once customers qualify and integrate new suppliers, switching back becomes expensive.
The letter calls for a whole-of-government response. Boost American production. Avoid subsidized imports. Protect the industrial base. Simple in principle. Harder in practice when laptops cost more and data centers wait on parts.
Memory has always followed boom-and-bust cycles. This time artificial intelligence amplifies the swings. Policymakers hope to break the pattern by favoring secure sources. Chinese firms hope to prove they can deliver reliable, affordable product. The coming months will test which side prevails.
One fact stands out. No easy answers exist. Short-term savings tempt buyers. Long-term vulnerabilities worry strategists. The debate over Chinese memory chips captures the larger contest for technology leadership. It will shape supply chains for years ahead.
