CXMT Shanghai (Pudong DRAM ‘Super Factory’) · 长鑫存储上海基地
ChangXin Memory Technologies (CXMT) | Memory
A genuinely new DRAM mega-fab, separate from CXMT’s Hefei headquarters site, entering substantive construction in March 2026 — this tracker did not capture it in an earlier pass, and it is one of the single largest individual under-construction projects in this entire dataset. Planned monthly capacity of 400,000-600,000 wafers would be 2-3x CXMT’s existing Hefei output.
Chinese name: 长鑫存储上海基地 (Chángxīn Cúnchǔ Shànghǎi Jīdì)
What does this facility make?
High-end DDR5 and LPDDR5X DRAM, plus a dedicated HBM3 line (50,000 wafers/month of the planned total) aimed at AI compute, server, and automotive-grade demand.
Why does it matter?
If completed on the stated schedule, this single fab would roughly double CXMT’s total DRAM capacity and push the company further up the global DRAM ranking — concrete evidence that the ‘many fabs under construction’ reality in China is larger than a facility-by-facility reading of status fields that lag real-time news can capture without active, repeated rechecking.
