Chinese memory chip maker CXMT has pushed its smartphone memory production closer to the level of established global players, a move that could shake up the market and draw tighter US export restrictions. The company's latest manufacturing process now allows it to produce DRAM chips for mobile devices at a scale and quality that rivals industry leaders, according to people familiar with the matter.
How CXMT caught up
CXMT, based in Hefei, has been working for years to close the gap with Samsung, SK Hynix, and Micron. Its new process node, reportedly around 17nm, brings its smartphone memory chips into the same performance and power-efficiency range as those from the top three. That's a big leap from just a few years ago, when CXMT was stuck on older, less competitive nodes.
The company's progress comes from a mix of licensed technology, in-house R&D, and aggressive investment. It now has the capacity to supply a meaningful share of the global smartphone DRAM market, which has long been dominated by the Korean and American giants.
If CXMT can sustain this momentum, it could drive down prices for smartphone memory and give handset makers more leverage in negotiations. That's good news for consumers but a headache for the incumbents, who have enjoyed fat margins on DRAM for years. The shift also threatens the current balance of power in the memory chip industry, where the top three control roughly 95% of the market.
But CXMT's rise isn't just a business story. It's a geopolitical one. The company is already on the US Entity List, which restricts American companies from selling it advanced equipment and software. Its latest breakthrough suggests those controls haven't fully stopped its progress.
Potential US export control response
Washington is watching. The Biden administration has been tightening export rules on semiconductor technology to China, and CXMT's advance could trigger another round of restrictions. Officials are reportedly considering new measures that would limit the sale of chip-making tools even for less advanced nodes, aiming to slow China's overall memory chip ambitions.
It's unclear exactly what form those controls would take. The US Commerce Department's Bureau of Industry and Security has not commented. But industry analysts say the move could target the specific equipment CXMT uses to produce its latest chips, potentially forcing the company to rely on older, less efficient tools.
For now, CXMT is pushing ahead. The company is ramping up production of its new memory chips and looking for customers beyond China. Whether it can sustain its momentum under tighter US export controls remains an open question.
