256 Kbit (32K x 8) AutoStore+ nvSRAM
Functional Description
The Cypress STK16C88-3 is a 256Kb fast static RAM with a
nonvolatile element in each memory cell. The embedded
nonvolatile elements incorporate QuantumTrap
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.
