Answer: nvSRAM is an SRAM plus nonvolatile (NV) product that has the same access speeds, interface pins, and random access features of a standard SRAM. On any power disruption (or on command), the SRAM data is moved into adjoining NV cells. When power is restored (or on command), the data is restored back to the SRAM and normal operation continues. This approach creates the fastest nonvolatile memory available today with absolutely no cell wear-out when using the SRAM.
