TSMC fabs don't make DRAM. Apple buys DRAM chips from the same handful of manufacturers that everyone else sources DRAM from.
- z9znz 4y agoI don't know much about this topic, but I have read that the RAM in M1/M2 machines is part of the Mx chip itself. Unless I misunderstand, I don't believe it's any kind of separate component - stick or otherwise.
- grandmczeb 4y agoThis is incorrect, just looking at the M2 promotional materials the DRAM is quite clearly a separate component[1]. The DRAM modules are combined with the M2 in a single package though, maybe that's what you're thinking of?

- z9znz 4y agoAhh ok, so it's not on the same die, but it's on the same package. Thus, it's not exactly something you can configure after the fact. In advance of configuration and sale, Apple has to decide to commit to some assortment of M2+RAM configurations.
