Value proposition

China's only domestic DRAM manufacturer with mass production capability, offering DDR4/DDR5/LPDDR4/LPDDR5 memory chips for mobile, PC, server, and AI applications at competitive pricing.

Products and solutions

DDR4/DDR5 SDRAM chips and modules, LPDDR4/LPDDR4X/LPDDR5/LPDDR5X mobile DRAM, HBM3 (in development), DRAM wafers for consumer and enterprise applications.

Unique value

China's only mass-production DRAM IDM; strategic national champion for semiconductor self-sufficiency; competitive DDR5 pricing matching global leaders; rapidly scaling production capacity (7.7% global DRAM share as of Q4 2025).

Target customer

Server/cloud providers (Alibaba Cloud, ByteDance, Tencent), PC manufacturers (Lenovo), smartphone makers (Xiaomi, OPPO, vivo, Honor, Transsion), and global memory module distributors.

Industries served

AI/Cloud Computing, Mobile Devices, Personal Computing, Servers & Data Centers, IoT, Virtual Reality, Automotive

Technology advantage

Advanced 16nm (10G1/10G2) process technology; licensed Qimonda DRAM IP portfolio; 3,116+ patents (2,348 invention patents); 12-inch wafer fabs in Hefei and Beijing; HBM3 packaging facility in Shanghai; 15,300+ employees with 4,653 R&D engineers.

How they differentiate

As China's sole mass-production DRAM maker, CXMT benefits from strong state backing, national semiconductor self-sufficiency policy support, lower cost base, and captive domestic demand from Chinese tech giants. Competes on pricing while rapidly closing the technology gap with global leaders.

Main competitors

Samsung Electronics, SK Hynix, Micron Technology

Key partnerships

WiLAN/Quarterhill (Qimonda DRAM patent license & acquisition), Rambus (DRAM patent license), Alibaba Cloud (strategic investor & customer), GigaDevice (strategic investor & affiliate), China Integrated Circuit Industry Investment Fund (Big Fund Phase II).

Notable customers
