Well IMO the real problem for CXMT is that the LPDDR5 demand will be way higher than what they can supply.
Juts for reference all
current ,
, and even all the
chips but the 8 series (i.e. 4, 6 and 7 series) use LPDDR4x or LPDDR5 memory. Only the very high end Snapdragon 8 and Mediatek Dimensity moved to LPDDR5x.
The big issue for CXMT, YMTC and SMIC at the moment is to ramp up production of their
current advanced nodes. They will easily sell all advanced chips they are able to produce, at least for the foreseeable future.
Ramp up production is the huge and very hard challenge for them considering that also exports of ASML DUVi machines starting 2024 will be limited and that the largest part of the domestic replacement for other kind of equipment is currently still in validation phase for advanced nodes below 28nm.
Apart from lithography, that is a (big) separated topic, Chinese SME have conquered 28nm in 2023. It will take them the whole 2024 and IMHO also 2025 to move down to 7nm
for volume production.
