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