Features

Functional Description

■

25 ns and 45 ns Access Times

The Cypress CY14B256LA is a fast static RAM, with a nonvol-

atile element in each memory cell. The memory is organized as

32K bytes of 8 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 opera-

tions are also available under software control.

Internally Organized as 32K x 8 (CY14B256LA)
