256 Kbit (32K x 8) AutoStore+ nvSRAM

Functional Description

The Cypress STK16C88 is a 256 Kb fast static RAM with a

nonvolatile element in each memory cell. The embedded

nonvolatile elements incorporate 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 cell. 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.
