Functional Description
The Cypress CY14E102L/CY14E102N is a fast static RAM, with
a nonvolatile element in each memory cell. The memory is
organized as 256K words of 8 bits each or 128K 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 reside 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.
