The SRAM provides the fast access & cycle times, ease of use, and unlimited read & write endurance of a normal SRAM. Data transfers automatically to the non-volatile stor- age 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 Simtek nvSRAM is the first monolithic non-vola- tile memory to offer unlimited writes and reads. It is the highest-performance, most reliable non-volatile memory available. 2Kx8 AutoStore nvSRAM BLOCK DIAGRAM COLUMN I/O COLUMN DEC STATIC RAM ARRAY 32 x 512 Quantum Trap 32 x 512 STORE/ RECALL CONTROL STORE RECALL POWER CONTROL A5 A6 A9 DQ0 DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 G E W A8 A7 A10 A3 A2 A0 A1 A4 VCCX VCAP HSB |
