32K x 8 nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• 25ns, 35ns and 45ns Access Times

The Simtek STK11C88 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 non-

volatile data resides in Nonvolatile Elements. Data

transfers from the SRAM to the Nonvolatile Elements

(the STORE operation), or from Nonvolatile Elements

to SRAM (the RECALL operation), are initiated using

a software sequence. Data transfers from the Non-

volatile Elements to the SRAM (the RECALL opera-

tion) also occur upon restoration of power.

• STORE to Nonvolatile Elements Initiated by

Software

• RECALL to SRAM Initiated by Software or

Power Restore

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

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

ments (Commercial/Industrial)

• 100-Year Data Retention in Nonvolatile Ele-

ments (Commercial/Industrial)

The STK11C88 is pin-compatible with industry-

standard SRAMs.

• Single 5V + 10% Operation

• Commercial and Industrial Temperatures

• 28-Pin PDIP and SOIC Packages
