FUNCTIONAL DESCRIPTION
The AS6nvLC512K8 / AS6nvLC256K16 is a fast static RAM, with a
nonvolatile element in each memory cell. The memory is organized as
512K bytes 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
innite 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.
