Functional Description
The Cypress CY14V256LA is a fast static RAM, with a nonvolatile element in each memory cell. The memory is organized as 32K bytes of 8 bits each. The embedded nonvolatile elements incorporate Quantum Trap technology, producing the world’s most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly reliable Quantum Trap cell. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down. On power-up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control.
