As a leading enterprise in China's DRAM industry, CXMT has made remarkable progress in the R&D and production of DDR5 memory chips in recent years. According to reports by TechPowerUp and MyDrivers, the yield rate of CXMT's DDR5 chips has reached 80%, which is a significant improvement from the 50% yield rate at the time of initial mass production, marking the company's increasing competitiveness in the global DRAM market. With the continuous advancement of technology and the expansion of production capacity, CXMT has become more and more important in the global semiconductor industry.
Leaps and bounds in DDR5 technology
DDR5 is the latest standard of mainstream memory technology, and its performance has been significantly improved compared with DDR4, including higher bandwidth and larger capacity, which can better meet the needs of high-performance computing, artificial intelligence, big data and other fields. CXMT has made an important breakthrough in the production process of DDR5, and has successfully increased the yield rate from 50% to 80%. This success means that CXMT's production capacity and technical level have gradually caught up with the world's leading DRAM manufacturers, enhancing its competitiveness in the global market.
It is expected that by 2025, the yield rate will further increase to 90%
CXMT's goal is to increase the yield rate of DDR5 chips to 90% by the end of 2025. In order to achieve this goal, CXMT is continuously optimizing the production process and increasing R&D investment. At the same time, with the increase of Fab 2's production capacity, it is expected to provide strong support for the expansion of its DDR5 production capacity. In the long run, with the improvement of production efficiency and the maturity of technology, CXMT is expected to occupy an increasingly important position in the global DRAM market.
Technological progress and capacity expansion
CXMT currently has two wafer fabs in Hefei. Fab 1 focuses on the production of DDR4 chips, using 19nm process, with a monthly production capacity of 100,000 wafers, and its yield rate has reached 90%. Fab 2 is dedicated to DDR5 production, using a more advanced 17nm process and currently has a monthly production capacity of 50,000 wafers. With the expansion of production capacity in 2025, the production capacity of Fab 2 is expected to increase by 50,000 wafers/month, which will greatly increase CXMT's production capacity in the DDR5 field.

In addition, CXMT's breakthrough in high-bandwidth memory (HBM2) technology is also noteworthy. Although major manufacturers in the market have begun mass production of HBM3 and HBM3E and plan to launch HBM4, CXMT has still made important progress on HBM2. It is expected that by mid-2025, CXMT will start small-batch production of HBM2 chips in its Fab 2 factory and provide important support for the rise of the domestic AI hardware market.
Growth in global market share
With the improvement of production and the progress of technology, the global market share of CXMT is also expanding. It is predicted that by the end of 2025, CXMT's market share will reach about 15%, compared with less than 2% three years ago, which is a huge increase. CXMT's monthly wafer production has also increased from 70,000 pieces in 2022 to an estimated 200,000 pieces in 2024, showing its continued expansion in terms of production capacity and market demand.
The rapid growth of CXMT is not only due to the expansion of its production capacity and the improvement of technology, but also because it can meet the needs of domestic and foreign customers for high-performance memory chips, especially in the fields of consumer electronics, artificial intelligence and data centers. With the continuous improvement of production and market share, CXMT will gradually become an important player in the global DRAM market, challenging the traditional DRAM giants.
Conclusion
CXMT's significant progress in DDR5 technology has not only enhanced China's position in the global DRAM market, but also promoted the development of the domestic storage industry. With the continuous breakthrough of CXMT in DDR5 and HBM2 technology, the company is expected to occupy an increasingly important role in the global semiconductor market. In the next few years, with the further expansion of production capacity and the continuous improvement of technical level, CXMT will continue to consolidate its competitiveness in the global DRAM market and become a force to be reckoned with in the global semiconductor industry.
