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.

^heW30 flash memory device also includes block lock-down and programmable

WAIT signal polarity, and is supported by an array of software tools.
