Functional Description
The Cypress CY14E256L is a fast static RAM with a nonvol-
atile element in each memory cell. The embedded nonvolatile
elements incorporate QuantumTrap technology producing the
world’s most reliable nonvolatile memory. The SRAM provides
Infinite 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.
A hardware STORE may be initiated with HSB pin.
