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?
The reason RAMis fast is because it doesn't have to store anything for any period of time. It is literally a place for running g programs to store data. Ram also is part of the CPU address space so each address in ram can be randomly read and written to.
