The SRAM provides the fast access & cycle times, ease of use, and unlimited read & write endurance of a normal SRAM. Data transfers under software control to the non-vol- atile storage cells (the STORE operation). On power-up, data is automatically restored to the SRAM (the RECALL operation). RECALL operations are also available under software control. The Simtek nvSRAM is the first monolithic non- volatile memory to offer unlimited writes and reads. It is the highest performance, most reliable non- volatile memory available.
