STK22C48

2K x 8 AutoStore™ nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

The Simtek STK22C48 is a fast static RAM with a

• 25ns, 35ns and 45ns Access Times

• “Hands-off” Automatic STORE with External

nonvolatile element incorporated in each static

memory cell. The SRAM can be read and written an

unlimited number of times, while independent, non-

volatile 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

V_CAPto 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 hard-

ware STORE may be initiated with the HSB pin.

68µF Capacitor on Power Down

• STORE to Nonvolatile Elements Initiated by

Hardware or AutoStore™ on Power Down

• Automatic RECALL on Power Up

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

• 1,000,000 STORE Cycles to Nonvolatile Ele-

ments

• 100-Year Data Retention in Nonvolatile Ele-

ments

• Single 5V + 10% Operation

• Commercial and Industrial Temperatures

• 28-Pin DIP and SOIC Packages
