摘要：After years of anticipation in the computer industry, byte-addressable NVM (non-volatile memory) now promises to augment or supplant volatile DRAM (dynamic RAM) in mainstream computers. 7 Like the ferrite core memory of the 1950s and 1960s, today's NVM retains data even when powered off. Though slower than DRAM, NVM is much faster than conventional durable media—HDDs (hard disk drives) and flash SSDs (solid-state drives). 10 Together with its high density and low cost per byte, NVM's speed and non-volatility will revolutionize memory/storage hierarchies designed around fast low-capacity volatile memory devices and slow high-capacity durable storage devices.
