General Description
The GL512/256/128N family of devices are 3.0V single power flash memory man-
ufactured using 110 nm
MirrorBit technology. The GL512N is a 512 Mbit,
organized as 33,554,432 words or 67,108,864 bytes. The GL256N is a 256 Mbit,
organized as 16,777,216 words or 33,554,432 bytes. The GL128N is a 128 Mbit,
organized as 8,388,608 words or 16,777,216 bytes. The devices have a 16-bit
wide data bus that can also function as an 8-bit wide data bus by using the BYTE#
input. The device can be programmed either in the host system or in standard
EPROM programmers.
Access times as fast as 90 ns (GL128N, GL256N) or 100 ns (GL512N) are
available.
Each device requires only a
single 3.0 volt power supply
for both read and
write functions. In addition to a V
CC
input, a high-voltage
accelerated program
(
WP#/
ACC)
input provides shorter programming times through increased cur-
rent. This feature is intended to facilitate factory throughput during system
production, but may also be used in the field if desired.
The devices are entirely command set compatible with the
JEDEC single-
power-supply Flash standard
. Commands are written to the device using
standard microprocessor write timing. Write cycles also internally latch addresses
and data needed for the programming and erase operations.
The
sector erase architecture
allows memory sectors to be erased and repro-
grammed without affecting the data contents of other sectors. The device is fully
erased when shipped from the factory.
Device programming and erasure are initiated through command sequences.
Once a program or erase operation has begun, the host system need only poll the
DQ7 (Data# Polling) or DQ6 (toggle)
status bits
or monitor the
Ready/Busy#
(RY/BY#)
output to determine whether the operation is complete. To facilitate
programming, an
Unlock Bypass
mode reduces command sequence overhead
by requiring only two write cycles to program data instead of four.
Hardware data protection
measures include a low V
CC
detector that automat-
ically inhibits write operations during power transitions.
Persistent Sector
Protection
provides in-system, command-enabled protection of any combina-
tion of sectors using a single power supply at V
CC
.
Password Sector Protection
prevents unauthorized write and erase operations in any combination of sectors
through a user-defined 64-bit password.
The
Erase Suspend/Erase Resume
feature allows the host system to pause an
erase operation in a given sector to read or program any other sector and then
complete the erase operation. The
Program Suspend/Program Resume
fea-
ture enables the host system to pause a program operation in a given sector to
read any other sector and then complete the program operation.
The
hardware RESET# pin
terminates any operation in progress and resets the
device, after which it is then ready for a new operation. The RESET# pin may be
tied to the system reset circuitry. A system reset would thus also reset the device,
enabling the host system to read boot-up firmware from the Flash memory
device.
The device reduces power consumption in the
standby mode
when it detects
specific voltage levels on CE# and RESET#, or when addresses have been stable
for a specified period of time.
