Numonyx™ Wireless Flash Memory (W30)
1.0
Introduction
The Numonyx™ Wireless Flash Memory (W30) device combines state-of-the-art
Numonyx™ Flash technology to provide a versatile memory solution for high
performance, low power, board constraint memory applications. The W30 flash memory
device offers a multi-partition, dual-operation flash architecture that enables the flash
device to read from one partition while programming or erasing in another partition.
This Read-While-Write or Read-While-Erase capability makes it possible to achieve
higher data throughput rates compared to single partition devices. Two processors can
interleave code execution, because program and erase operations can now occur as
background processes.
The
W30 flash memory device
incorporates an Enhanced Factory Programming (EFP)
mode to improve 12 V factory programming performance. This feature helps eliminate
manufacturing bottlenecks associated with programming high-density flash memory
devices. The EFP program time is 3.5 µs per word, compared to the standard factory
program time of 8.0 µs per word, so EFP mode saves significant factory programming
time for improved factory efficiency.
T
he
W30 flash memory device
also includes block lock-down and programmable
WAIT signal polarity, and is supported by an array of software tools.
