If we have ssd’s that exceed the 2tb mark, why are RAM modules still limited in size?

Question

I understand that even the fastest nvme drive is way slower than RAM, but surely that isn’t the only reason we don’t see 1tb memory modules on the market. I was only able to find 512gb modules in my searching, and that was for servers.

Answer 1

Because we don’t need them yet. That’s it, really.

Also, there are certain advantages of having multiple memory modules vs one big one. Multi-channel mode is the key example.
