China's current memory capability

Fred Chen

It looks like in both DRAM and NAND it is at a level equivalent to "2y" when referred to Samsung, Micron, or SKHynix. TechInsights analyzed a CXMT '2x' (22nm D/R) part which actually looks closer in cell size to a mainstream '2y':

SMIC is mass producing 24 nm SLC NAND for GigaDevice currently. It is unique that the foundry produces standalone Flash NVM.

YMTC has announced 128-layer 3D NAND, but its backing company Tsinghua Unigroup has some financial troubles.

All nice, but one problem though. CXMT would've been at a deep loss if not for near zero tax rate from subsidies.

The blast from HSMC is now spreading onto CXMT, and may well pull the financial rug from under them.

Samsung on other band swims in cash every day.
