... Document Number: 001-50638 Rev Kbit ( SoftStore nvSRAM Functional Description The Cypress STK11C68 is a 64Kb fast static RAM with a nonvol- atile element in each memory cell. The embedded nonvolatile elements incorporate QuantumTrap technology producing the world’s most reliable nonvolatile memory. The SRAM provides unlimited read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell ...
