GENERAL DESCRIPTION
The Am29LV800D is an 8 Mbit, 3.0 volt-only Flash
memory organized as 1,048,576 bytes or 524,288
words. The device is offered in 48-ball FBGA, 44-pin
SO, and 48-pin TSOP packages. For more informa-
tion, refer to publication number 21536. The
word-wide data (x16) appears on DQ15–DQ0; the
byte-wide (x8) data appears on DQ7–DQ0. This de-
vice requires only a single, 3.0 volt V
CC
supply to per-
form read, program, and erase operations. A standard
EPROM programmer can also be used to program and
erase the device.
This device is manufactured using AMD’s 0.23 µm pro-
cess technology, and offers all the features and bene-
fits of the Am29LV800B, which was manufactured
using 0.32 µm process technology.
The standard device offers access times of 70, 90, and
120 ns, allowing high speed microprocessors to oper-
ate without wait states. To eliminate bus contention the
device has separate chip enable (CE#), write enable
(WE#) and output enable (OE#) controls.
The device requires only a
single 3.0 volt power sup-
ply
for both read and write functions. Internally gener-
ated and regulated voltages are provided for the
program and erase operations.
The device is entirely command set compatible with
the
JEDEC single-power-supply Flash standard.
Commands are written to the command register using
standard microprocessor write timings. Register con-
tents serve as input to an internal state-machine that
controls the erase and programming circuitry. Write
cycles also internally latch addresses and data
needed for the programming and erase operations.
Reading data out of the device is similar to reading
from other Flash or EPROM devices.
Device programming occurs by executing the program
command sequence. This initiates the
Embedded
Program
algorithm—an internal algorithm that auto-
matically times the program pulse widths and verifies
proper cell margin. The
Unlock Bypass
mode facili-
tates faster programming times by requiring only two
write cycles to program data instead of four.
Device erasure occurs by executing the erase com-
mand sequence. This initiates the
Embedded Erase
algorithm—an internal algorithm that automatically
preprograms the array (if it is not already programmed)
before executing the erase operation. During erase,
the device automatically times the erase pulse widths
and verifies proper cell margin.
The host system can detect whether a program or
erase operation is complete by observing the RY/BY#
pin, or by reading the DQ7 (Data# Polling) and DQ6
(toggle)
status bits.
After a program or erase cycle
has been completed, the device is ready to read array
data or accept another command.
The
sector erase architecture
allows memory sec-
tors to be erased and reprogrammed without affecting
the data contents of other sectors. The device is fully
erased when shipped from the factory.
Hardware data protection
measures include a low
V
CC
detector that automatically inhibits write opera-
tions during power transitions. The
hardware sector
protection
feature disables both program and erase
operations in any combination of the sectors of mem-
ory. This can be achieved in-system or via program-
ming equipment.
The
Erase Suspend
feature enables the user to put
erase on hold for any period of time to read data from,
or program data to, any sector that is not selected for
erasure. True background erase can thus be achieved.
The
hardware RESET# pin
terminates any operation
in progress and resets the internal state machine to
reading array data. The RESET# pin may be tied to
the system reset circuitry. A system reset would thus
also reset the device, enabling the system micropro-
cessor to read the boot-up firmware from the Flash
memory.
The device offers two power-saving features. When
addresses have been stable for a specified amount of
time, the device enters the
automatic sleep mode.
The system can also place the device into the
standby mode.
Power consumption is greatly re-
duced in both these modes.
AMD’s Flash technology combines years of Flash
memory manufacturing experience to produce the
highest levels of quality, reliability and cost effective-
ness. The device electrically erases all bits within
a sector simultaneously via Fowler-Nordheim tunnel-
ing. The data is programmed using hot electron injec-
