STK14D88-3

32K x 8 AutoStore^TMnvSRAM

QuantumTrap^TMCMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• 25ns, 35ns and 45ns Access Times

• “Hands-off” Automatic STORE on Power Down

with only a small capacitor

• STORE to QuantumTrap™ Nonvolatile

Elements is Initiated by Software , device pin

or AutoStore™ on Power Down

The Simtek STK14D88-3 is a fast static RAM with a

nonvolatile element in each memory cell. The

embedded

nonvolatile

elements

incorporate

Simtek’s 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^TMcell. 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.

• RECALL to SRAM Initiated by Software or

Power Restore

• Unlimited READ, WRITE and RECALL Cycles

• 5mA Typical I_CCat 200ns Cycle Time

• 1,000,000 STORE Cycles to QuantumTrap™

• 100-Year Data Retention to QuantumTrap™

• Single 3V +20%, -10% Operation

• Commercial and Industrial Temperatures

• SSOP and SOIC Packages

• RoHS Compliance
