FUNCTIONAL DESCRIPTION
The Austin Semiconductor AS8nvC512K32 is a fast static RAM,
with a nonvolatile element in each memory cell. The memory is
organized as 512K bytes of 8 bits for each of 4 die to form 512Kx32.
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.
