2.0 PRINCIPLES OF OPERATION

The Word-Wide FlashFile memories include an

on-chip Write State Machine (WSM) to manage

block erase, program, and lock-bit configuration

functions. It allows for: 100% TTL-level control

inputs, fixed power supplies during block erasure,

programming, lock-bit configuration, and minimal

processor overhead with RAM-like interface

timings.

After initial device power-up or return from deep

power-down mode (see Bus Operations), the

device defaults to read array mode. Manipulation

of external memory control pins allow array read,

standby, and output disable operations.
