Chipmakers make abundant use of two very different functional classes of memory in their products. For operational use (main/primary memory) where speed is critical, DRAM and SRAM are employed, ...

There was a time when the hierarchy of persistent storage products consisted of just disk and NAND flash storage. But today a new layer has become possible, between disk/SSD and memory. It is often ...

Storage-class memory (SCM), RAM that has the ability to retain its contents like NAND flash memory but the speed of DRAM, will eventually supplant flash as the high-speed storage medium of choice.

Storage performance is never good enough. DRAM speeds are measured in nanoseconds, but is volatile/non-persistent, meanwhile, even the fastest non-volatile storage – such as Intel Optane/3D XPoint – ...
