Non-volatile random-access memory

random-access memory that retains its information when power is turned off (non-volatile),in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied

Non-volatile random-access memory (NVRAM) is a type of computer memory. It is permanent storage similar to a hard drive. The startup configuration is stored in NVRAM. The best known form of NVRAM today is the flash drive.
