Functional Description
The Cypress CY14B104LA/CY14B104NA is a fast static RAM
(SRAM), with a nonvolatile element in each memory cell. The
memory is organized as 512 K bytes of 8 bits each or 256 K
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.
