STK15C88

32K x 8 AutoStore™ nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• Nonvolatile Storage without Battery Problems

The STK15C88 is a fast SRAM 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 using charge stored in system capacitance.

Transfers from the nonvolatile elements to the SRAM

(the RECALL operation) take place automatically on

restoration of power. Initiation of STORE and RECALL

cycles can also be controlled by entering specific

read sequences. The STK15C88 is pin-compatible

with 32k x 8 SRAMs and battery-backed SRAMs,

allowing direct substitution while enhancing perfor-

mance. A similar device (STK16C88) with an inter-

nally integrated capacitor is available for

applications with very fast power-down slew rates.

The STK14C88, which uses an external capacitor, is

another alternative for these applications.

• Directly Replaces 32K x 8 Static RAM, Battery-

Backed RAM or EEPROM

• 25ns, 35ns and 45ns Access Times

• STORE to nonvolatile elements Initiated by

Software or AutoStore™

• 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

• 100-Year Data Retention in nonvolatile ele-

ments (Commercial/Industrial)

• Single 5V + 10% Operation

• Commercial and Industrial Temperatures

• 28-Pin PDIP and SOIC Packages
