China will accelerate memory production to take advantage of shortages—CXMT and YMTC aim to profit from the deficit.

Chinese memory giants accelerate expansion while South Korean and American competitors postpone plans

Company What is being done When launch is planned
CXMT (China’s largest DRAM maker) Increase capacity in Shanghai, introduce new lines for DDR‑4/DDR‑5 and HBM Equipment installation – second half of 2024; mass production – 2025
YMTC (China’s largest NAND maker) Build a new plant in Wuhan, part of the capacity will be allocated to DRAM and HBM Operational activity – end of 2024, production launch – early 2025

Why China reacts so quickly
1. High domestic demand
- CXMT plants in Hefei and Beijing are running at full capacity, and the consumer electronics and server market is growing.

2. Government support
- Import substitution policy and subsidies allow companies to scale up quickly without external constraints.

What competitors offer
- Samsung, SK hynix, Micron
– Plan to expand capacity only in a few years to avoid overloading current lines.

- Chinese players (CXMT and YMTC)
– Ready to launch new lines already next year, showing a more decisive approach.

Technical nuances
Company Current situation Future
YMTC After U.S. sanctions the company overcame technological barriers and completed development of its own DRAM types. Plans mass production of DRAM and HBM to meet the domestic AI accelerator market.
CXMT Participating in DDR5 and HBM, already holds 11.1 % of the global DRAM market. Expected share growth to 13.9 % by end‑2027; company is preparing for an IPO to raise up to $4.25 bn.

Impact on the global market
- YMTC could lift its DRAM share from 12 % to 15 % of global volume by 2028.
- CXMT already supplies leading Chinese OEMs and aims to expand its DDR5/HBM lineup, strengthening its position as the world’s fourth‑largest DRAM producer.

Conclusion
Chinese companies CXMT and YMTC demonstrate an aggressive growth strategy to quickly meet rising demand for memory in servers, PCs, automotive electronics, and AI accelerators. While global players postpone capacity expansion, the Chinese market will see new lines within the next year, potentially shifting the balance of power in the memory industry.
