[Simtek]
DESCRIPTION
The Simtek STK22C48 is a fast static RAM with a nonvolatile 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 Nonvolatile Elements. Data transfers from the SRAM to the Nonvolatile Elements (the STORE operation) can take place automatically on power down. A 68µF or larger capacitor tied from VCAP to ground guarantees the STORE operation, regardless of power-down slew rate or loss of power from “hot swapping”. Transfers from the Nonvolatile Elements to the SRAM (the RECALL operation) take place automatically on restoration of power. A hardware STORE may be initiated with the HSB pin.
