As far as I can tell, Micron and SK Hynix are using EUV lithography and may be constrained by availability of the equipment, whereas CXMT does not have EUV machines. There were reports that EUV lithography is needed for high yields, but CXMT appears to be proving that wrong.

Seems it's mostly useful for LPDDR modules which are predominantly used in battery-powered devices and to improve margins.
