Functional Description
The Cypress CY14B104L/CY14B104N is a fast static RAM,
with a nonvolatile element in each memory cell. The memory
is organized as 512K words of 8 bits each or 256K words of 16
bits each. 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.
