(Non-Volatile RAM) - A typically small amount of RAM that stores information even after you turn off your computer. It is used in modems for storing your settings and in hardware keys for protecting software. Flash memory is a type of non-volatile RAM.
nonvolatile RAM. RAM that retains its contents when a unit is powered off. In Cisco products, NVRAM is used to store configuration information.
Non-volatile random access memory (NVRAM) is the general name used to describe any type of random access memory which does not lose its information when power is turned off. This is in contrast to the most common forms of random access memory today, DRAM and SRAM, which both require continual power in order to maintain their data. NVRAM is a subgroup of the more general class of non-volatile memory types, the difference being that NVRAM devices offer random access, as opposed to sequential access like hard disks.
