Functional Description

20 ns, 25 ns, and 45 ns Access Times
The Cypress CY14B101LA/CY14B101NA is a fast static RAM,
with a nonvolatile element in each memory cell. The memory is
■
Internally Organized as 128K x 8 (CY14B101LA) or 64K x 16
(CY14B101NA)
organized as 128K bytes of 8 bits each or 64K 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.
