So, to ask a dumb question, what does make something RAM?
My take on RAM is that RAM is just another device; the only
difference is that you want to be able to implement fast
paths that go straight(ish) to target memory; but that's
an optimisation detail, not something that makes RAM
conceptually different from other devices...
