STK11C88-N20中文资料32K x 8 nvSRAM QuantumTrap™ CMOS Nonvolatile Static RAM数据手册SIMTEK规格书

描述 Description

DESCRIPTION
The Simtek STK11C88 is a fast static RAM with a nonvolatile, electrically erasable  PROM element
incorporated in each static memory cell. The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data transfers from the  SRAMto the EEPROM(the STOREoperation), or from EEPROM to SRAM(the RECALLoperation), take place using a software sequence. Transfers from the EEPROM to the SRAM(the RECALLoperation) also take place automatically on restoration of power.FEATURES
