To copy my comment on the beehaw.org post, because they and lemmy.world aren’t federated:

This deal may make matters worse for more buyers, because PSMC used the Tongluo site to make legacy DRAM products – the kind of memory used in less advanced products. With the company now exiting the legacy chip biz, that memory will also become more scarce, giving the laws of supply and demand another moment in which to work their way on markets.

PSMC’s current DRAM capacity mainly relies on 25nm and 38nm nodes, which restricts DDR4 production to lower-density products.

I guess that that’s more DDR4 supply drying up. It’s going to be some very scarce years for memory until enough new production comes online.
