Flash Memory Features
SOFTWARE FEATURES
(Am29DL640G/Am29DL320G)
■ Supports Common Flash Memory Interface (CFI)
—
Features apply to Am29DL640G and Am29DL320G
independently.
■ Program/Erase Suspend/Erase Resume
—
Suspends program/erase operations to allow
programming/erasing in same bank
ARCHITECTURAL ADVANTAGES
■ Data# Polling and Toggle Bits
■ Simultaneous Read/Write operations
—
Provides a software method of detecting the status of
program or erase cycles
—
Data can be continuously read from one bank while
executing erase/program functions in another bank.
Zero latency between read and write operations
—
HARDWARE FEATURES
■ Flexible Bank architecture
■ Any combination of sectors can be erased
—
Read may occur in any of the three banks not being written
■ Ready/Busy# output (RY/BY#)
or erased.
—
Hardware method for detecting program or erase cycle
completion
—
Four banks may be grouped by customer to achieve desired
bank divisions.
■ Hardware reset pin (RESET#)
■ Manufactured on 0.17 µm process technology

Extra 256 byte sector on Am29DL320G
■ WP#/ACC input pin
—
Write protect (WP#) protects sectors 0, 1, 140, and 141 in
Factory locked and identifiable: 16 bytes available for
secure, random factory Electronic Serial Number; verifiable
as factory locked through autoselect function. ExpressFlash
option allows entire sector to be available for
factory-secured data
Am29DL640G, and two outermost boot sectors in
Am29DL320G
—
Acceleration (ACC) function accelerates program timing
■ Sector protection
—
Customer lockable: Sector is one-time programmable. Once
sector is locked, data cannot be changed.
—
Hardware method of locking a sector, either in-system or
using programming equipment, to prevent any program or
■ Zero Power Operation
Sophisticated power management circuits reduce power
consumed during inactive periods to nearly zero.
■ Boot sectors
erase operation within that sector
Temporary Sector Unprotect allows changing data in
protected sectors in-system
