Changxin Memory Technology (CXMT), a leading Chinese memory semiconductor company, announced the mass production of its 5th generation technology platform, claiming it has established a technological breakthrough to compete with industry leaders such as Samsung Electronics, SK Hynix, and Micron Technology.
On September 20, CXMT officially unveiled its 5th generation technology platform at the 2026 World Manufacturing Conference held in Hefei, Anhui Province, China, according to reports from Chinese media including Pengpai News and Reuters.
The company explained that the new platform allows for the production of higher-performance memory chips at lower costs and power consumption compared to previous generations.
Specifically, the new platform has reduced the circuit spacing within memory chips to 11.95 nanometers by applying a 'quadruple patterning' technique, which involves repeating the same manufacturing process multiple times to create finer circuit patterns.
Luo Xiaodong, CXMT's vice president, stated, "Our current process technology level is on par with the most advanced processes being mass-produced in the industry."
With this advancement in miniaturization, CXMT has significantly increased memory density. According to the company, the 5th generation platform can produce at least 50% more chips per wafer compared to the 4th generation platform, improving both power efficiency and cost competitiveness.
CXMT also introduced two types of 24Gb LPDDR5X products based on the 5th generation platform. LPDDR5X is a low-power DRAM primarily used in mobile devices such as smartphones. Both products can store 50% more data than existing counterparts and have already entered mass production, supplying major Chinese smartphone manufacturers with flagship products.
With this mass production, CXMT expects to contribute to the diversification of the global memory market supply chain.
This technological advancement comes amid ongoing U.S. export restrictions on semiconductor technology to China, as the country seeks to reduce its reliance on foreign technology. Since 2022, the U.S. has limited China's access to advanced semiconductors, semiconductor manufacturing equipment, and related software.
CXMT has been rapidly increasing its market share in the global DRAM sector, intensifying competition with Samsung and SK Hynix. According to market research firm Counterpoint Research, CXMT's global DRAM market share rose from 4% in the second quarter of last year to 10% in the second quarter of this year.
The company's revenue in the first half of this year increased nearly tenfold compared to the same period last year, and it has turned a profit.
Goldman Sachs projects that CXMT could supply about half of China's DRAM demand and up to 40% of the country's HBM demand by 2028.
