THIS SPEC IS OBSOLETE Spec No: 001-51592 Spec Title: STK14CA8 128KX8 AUTOSTORE NVSRAM Sunset Owner: Girija Chougala (GVCH) Replaced by: NoneSTK14CA8 128Kx8 AutoStore nvSRAM Features Description 1 25 , 35, 45 ns Read Access and Read/Write Cycle Time The Cypress STK14CA8 is a 1 Mb fast static RAM with a nonvol- atile QuantumTrap storage element included with each memory Unlimited Read/Write Endurance cell. This SRAM provides fast access and cycle times, ease of use, and unlimited read and write endurance of a normal SRAM. Automatic Nonvolatile STORE on Power Loss Data transfers automatically to the nonvolatile storage cells Nonvolatile STORE Under Hardware or Software Control when power loss is detected (the STORE operation). On power Automatic RECALL to SRAM on Power Up up, data is automatically restored to the SRAM (the RECALL operation). Both STORE and RECALL operations are also Unlimited RECALL Cycles available under software control. 200K STORE Cycles The Cypress nvSRAM is the first monolithic nonvolatile memory to offer unlimited writes and reads. It is the highest performing 20-Year Nonvolatile Data Retention and most reliable nonvolatile memory available.
