China’s CXMT Says New DRAM Platform Enters Mass Production, Challenging Samsung and SK Hynix

Chinese memory-chip maker CXMT said Sunday that its fifth-generation technology platform has entered mass production, marking a significant advance in Beijing’s effort to build a domestic competitor to Samsung Electronics, SK Hynix and Micron Technology in the global DRAM market.

The Hefei-based company said the new platform can produce more powerful memory chips at lower cost and with lower power consumption, giving Chinese electronics manufacturers another domestic source of DRAM for smartphones and other devices.

The announcement is particularly significant because DRAM is a foundational component of modern electronics. It provides the short-term working memory used by smartphones, computers, servers, and other devices to run applications and process data.

CXMT is China’s leading DRAM producer and has been expanding its technological capabilities as Beijing pushes to reduce the country’s dependence on foreign semiconductor suppliers. The company listed on Shanghai’s STAR Market this year, giving it access to domestic capital as it expands production.

The fifth-generation platform is designed to improve both chip density and manufacturing efficiency. CXMT said it has reduced the spacing of key features in the data-storage portion of its chips to 11.95 nanometers, allowing more memory to be packed into each chip and more individual dies to be produced from every silicon wafer.

The company said it achieved the advance using quadruple patterning, a manufacturing technique that repeats lithography steps to create fine circuit patterns.

“Our process capability is now on par with the most advanced mass-produced nodes out there in the industry,” Luo Xiaodong, CXMT’s vice president and head of its marketing center, said at the 2026 World Manufacturing Convention in Hefei.

That claim, if sustained in commercial production, would narrow an important technological gap between CXMT and the established global memory-chip leaders.

CXMT Targets Smartphone Memory Market

CXMT also unveiled two 24-gigabit LPDDR5X products manufactured using the new platform. LPDDR5X is a low-power form of DRAM widely used in smartphones and other portable electronics. The company said the new products can hold 50% more data than its previous equivalent products and have already entered mass production. They are available in two package formats intended for different smartphone and portable-device designs.

CXMT said the new manufacturing platform can generate at least 50% more gross chip dies per wafer than its fourth-generation technology, based on an 8-gigabit chip baseline. The figure is important because wafer productivity directly affects the economics of semiconductor manufacturing. Producing more dies from each wafer can lower the amount of silicon required for every chip and potentially improve manufacturing costs.

CXMT clarified that the 50% increase refers to the gross number of potential dies produced from a wafer before defective chips are removed. It therefore does not represent a 50% increase in the proportion of chips that successfully pass final testing.

The company said it developed the new platform through computer simulations and cooperation with Chinese semiconductor equipment manufacturers on critical production processes.

That approach is also considered bold and defiant in the context of U.S. restrictions on China’s semiconductor industry.

Since 2022, Washington has tightened export controls covering advanced semiconductor manufacturing equipment, software and other technologies that China can access. The restrictions have complicated Beijing’s efforts to develop cutting-edge chips using the same equipment and production ecosystems available to companies in South Korea, Taiwan and the United States.

CXMT’s progress therefore represents more than a commercial push into the memory market. Many see it also as a test of whether Chinese semiconductor manufacturers can continue advancing through domestic engineering, equipment development and manufacturing improvements while operating with more limited access to foreign technology.

A Bigger Challenge for Global Memory Makers

Samsung, SK Hynix and Micron currently dominate the global DRAM industry, making CXMT’s expansion a potential source of additional competition in a market where manufacturing scale and technological sophistication are critical.

But the emergence of a larger Chinese supplier could have implications for both prices and supply chains, particularly in lower-power memory used in consumer electronics.

CXMT’s latest products are initially focused on smartphones and other portable devices rather than demonstrating that the company has matched the leaders across every segment of the DRAM market. The company’s claim that its process capability is comparable with advanced mass-produced nodes is also a company statement rather than an independently verified assessment.

Still, moving a new technology platform into mass production is materially different from demonstrating a chip in a laboratory or announcing a prototype. It suggests CXMT has reached a stage where the technology can be incorporated into commercial manufacturing at scale.

The economics of that production will ultimately determine how significant the advance becomes.

China remains one of the world’s largest electronics manufacturing hubs, creating a large potential domestic market for locally produced memory. Chinese smartphone and electronics manufacturers could benefit from having an additional supplier, while CXMT can use domestic demand to increase production volumes and gather manufacturing experience.

The company is also entering the market at a time when memory has become increasingly important to the artificial intelligence industry. DRAM and higher-performance memory technologies are essential components of the computing systems used in data centers, although the requirements of AI accelerators are increasingly centered on high-bandwidth memory, or HBM, a more specialized segment where Samsung and SK Hynix remain major players.

CXMT’s progress does not immediately translate into a challenge across the entire memory industry. But a stronger domestic DRAM producer gives China a broader foundation from which to develop more advanced memory technologies.

That is precisely what makes the company’s fifth-generation platform important to Beijing’s wider semiconductor ambitions. China is not simply trying to replace individual imported chips. It is attempting to develop a complete domestic semiconductor ecosystem spanning chip design, manufacturing, equipment and materials.

CXMT’s ability to increase the number of dies produced from each wafer while reducing feature spacing points to progress on the manufacturing side of that effort.

However, industry analysts say the next test will be whether those gains can translate into reliable yields, competitive costs and sustained commercial volumes. If CXMT can achieve those targets, the company could become a more significant force in global DRAM supply and further reduce Chinese electronics manufacturers’ dependence on Samsung, SK Hynix and Micron.

This means for the established memory leaders, another competitive variable in an industry already undergoing a major investment cycle driven by smartphones, data centers and AI infrastructure.
