Random question that crossed my mind yesterday:
In the era of NVME and SSDs, why is RAM still a thing? Is there any reason (other than technological inertia) that we should have two different kinds of memory, when the primary reason for that is no longer relevant?
RAM can serve up data in memory 1000 times faster than a NVMe drive
Also RAM doesn't have a limited number of lifetime writes.
Yes, I get that. But I'm really wondering why that is? If memory is digital, and storage is digital, why not develop a RAM-less architecture? Why not have a storage bus with the same throughput as memory does currently? Is it just because of the cost of the chips?
