CXMT (ChangXin Memory Technologies) is China's largest DRAM integrated device manufacturer, producing DDR5, LPDDR5, and LPDDR5X memory chips.
Micron Technology designs, manufactures, and sells memory (DRAM, NAND) and storage products, including high-bandwidth memory for AI accelerators.
The Verdict: CXMT vs Micron
Micron and CXMT are both DRAM makers, but at very different stages. Micron, founded in 1978 in Boise, Idaho, is a 47-year-old American incumbent with a market cap of roughly $1.148T and FY2025 revenue of about $37.4B (up nearly 50% year over year) as AI accelerators drove demand for its high-bandwidth memory. CXMT (ChangXin Memory Technologies), founded in 2017 in Hefei, China, is the country's largest DRAM manufacturer and the world's fourth-largest โ it raised roughly RMB29.5B (~$4.2B) in its 2026 Shanghai STAR Market IPO, with shares reportedly surging nearly 500% on debut; investors linked to the Hefei municipal government hold about 36.8% of the company, with no single controlling shareholder. No dated, sourceable market-cap figure for CXMT exists yet, so this page compares what's on record rather than estimating one.
The strategic story matters more than the size gap: CXMT exists largely to give China a domestic alternative to Micron, Samsung, and SK Hynix amid export controls on advanced memory technology, while Micron is riding the AI-driven HBM boom as an established, diversified global supplier. Readers tracking the US memory incumbent and its AI exposure should watch Micron; readers tracking China's push for chip self-sufficiency should watch CXMT.
