GENERAL DESCRIPTION
The Am29LV800B in Known Good Die (KGD) form is
an 8 Mbit, 3.0 volt-only Flash memory. AMD defines
KGD as standard product in die form, tested for functionality and speed. AMD KGD products have the same
reliability and q uality as AMD produc ts in packaged
form.
The host system can detect whether a program or
erase operation is complete by observing the RY/BY#
pin, or by re ading the DQ7 (D ata# 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.
Am29LV800B Features
The Am29LV800B is an 8 Mbit, 3.0 volt-only Flash
memory organized as 1,048,576 bytes or 524,288
words. The word-w ide data (x16) ap pears on DQ15–
DQ0; the byte-wide (x 8) data appears on D Q7–DQ0.
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 p owersupply for both read and write functions. Internally
generated and regulated voltages are provided for the
program and erase operations. No V
program or erase operations. The device can also be
programmed in standard EPROM programmers.
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 contents
serve as input to an internal state-machine that controls the erase and programming circuitry. Write cycles
also internally latch addresses and data n eeded 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 EmbeddedProgram algorithm—an internal algorithm that automatically times the program pulse widths and verifies
proper cell margin. The Unlock Bypass mode facili-
tates faster program ming times by req uiring only two
write cycles to program data instead of four.
Device erasure occurs by executing the erase
command sequence. This initiates the EmbeddedErase 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 t i mes t he erase
pulse widths and verifies proper cell margin.

PP
The sec tor erase arc hitecture allows memory sectors
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
detector that automatically inhibits write opera-
V
CC
tions during p ower transitions. The hardware sector
protection feature disables both program and erase
operations in any combination of the sectors of
memory. This can be achieved in-system or via programming equipment.
The Er ase 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 microprocessor
to read the boot-up firmware from the Flash memory.
The device offers two pow er-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 standbymode. Power consumption is greatly reduced 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 effectiveness. The device e lectrically erases a ll b its wit hin
a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron
injection.
