www.DataSheet4U.com STK11C88 32Kx8 SoftStore nvSRAM DESCRIPTION The Simtek STK11C88 is a 256Kb fast static RAM with a non-volatile Quantum Trap storage element included with each memory cell. 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-volatile storage cell (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 nonvolatile memory to offer unlimited writes and reads. It is the highest performance, most reliable nonvolatile memory available.
