GENERAL DESCRIPTION
The Am29SL800D is an 8 Mbit, 1.8 V volt-only Flash
memory organized as 1,048,576 bytes or 524,288
words. The device is offered in 48-pin TSOP and 48ball FBGA packages. The word-wide data (x16)
appears on DQ15–DQ0; the byte-wide (x8) data
appears on DQ7–DQ0. This device is designed to be
programmed and erased in-system with a single 1.8
volt VCC supply. No VPP is for write or erase operations.
The device can also be programmed in standard
EPROM programmers.
The standard device offers access times of 90, 100,
120, and 150 ns, allowing high speed microprocessors
to operate 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 1.8 volt power
supply for both read and write functions. Internally
generated 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 contents 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 automatically times the program pulse widths and verifies
proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two
write cycles to program data instead of four.
Device erasure occurs by executing the erase
command 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.
2
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 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
VCC detector that automatically inhibits write operations during power 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 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 microprocessor
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 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 electrically erases all bits within a
sector simultaneously via Fowler-Nordheim tunneling.
The data is programmed using hot electron injection.

DEVICE BUS OPERATIONS
This section describes the requirements and use of the
device bus operations, which are initiated through the
internal command register. The command register itself
does not occupy any addressable memory location.
The register is composed of latches that store the commands, along with the address and data information
needed to execute the command. The contents of the
Table 1.
register serve as inputs to the internal state machine.
The state machine outputs dictate the function of the
device. Table 1 lists the device bus operations, the
inputs and control levels they require, and the resulting
output. The following subsections describe each of
these operations in further detail.

pins DQ15–DQ0 operate in the byte or word configuration. If the BYTE# pin is set at logic ‘1’, the device is in
word configuration, DQ15–DQ0 are active and controlled by CE# and OE#.
If the BYTE# pin is set at logic ‘0’, the device is in byte
configuration, and only data I/O pins DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O
pins DQ8–DQ14 are tri-stated, and the DQ15 pin is
used as an input for the LSB (A-1) address function.
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE# and OE# pins to VIL. CE# is the power
control and selects the device. OE# is the output
control and gates array data to the output pins. WE#
should remain at V IH . The BYTE# pin determines
whether the device outputs array data in words or
bytes.
March 17, 2003
The internal state machine is set for reading array data
upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory
content occurs during the power transition. No
command is necessary in this mode to obtain array
data. Standard microprocessor read cycles that assert
valid addresses on the device address inputs produce
valid data on the device data outputs. The device
remains enabled for read access until the command
register contents are altered.
See “Reading Array Data” for more information. Refer
to the AC Read Operations table for timing specifications and to Figure 13 for the timing diagram. ICC1 in
the DC Characteristics table represents the active
current specification for reading array data.
Writing Commands/Command Sequences
To write a command or command sequence (which
includes programming data to the device and erasing
sectors of memory), the system must drive WE# and
CE# to VIL, and OE# to VIH.
Am29SL800D

A D V A N C E
I N F O R M A T I O N
For program operations, the BYTE# pin determines
whether the device accepts program data in bytes or
words. Refer to “Word/Byte Configuration” for more
information.
The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the
Unlock Bypass mode, only two write cycles are
required to program a word or byte, instead of four. The
“Word/Byte Program Command Sequence” section
has details on programming data to the device using
both standard and Unlock Bypass command
sequences.
An erase operation can erase one sector, multiple sectors, or the entire device. Tables 2 and 3 indicate the
address space that each sector occupies. A “sector
address” consists of the address bits required to
uniquely select a sector. The “Command Definitions”
section has details on erasing a sector or the entire
chip, or suspending/resuming the erase operation.
After the system writes the autoselect command
sequence, the device enters the autoselect mode. The
system can then read autoselect codes from the
internal register (which is separate from the memory
array) on DQ7–DQ0. Standard read cycle timings
apply in this mode. Refer to the Autoselect Mode and
Autoselect Command Sequence sections for more
information.
ICC2 in the DC Characteristics table represents the
active current specification for the write mode. The “AC
Characteristics” section contains timing specification
tables and timing diagrams for write operations.
Program and Erase Operation Status
During an erase or program operation, the system may
check the status of the operation by reading the status
bits on DQ7–DQ0. Standard read cycle timings and ICC
read specifications apply. Refer to “Write Operation
Status” for more information, and to “AC Characteristics” for timing diagrams.
Standby Mode
When the system is not reading or writing to the device,
it can place the device in the standby mode. In this
mode, current consumption is greatly reduced, and the
outputs are placed in the high impedance state, independent of the OE# input.
The device enters the CMOS standby mode when the
CE# and RESET# pins are both held at VCC ± 0.2 V.
(Note that this is a more restricted voltage range than
VIH.) If CE# and RESET# are held at VIH, but not within
VCC ± 0.2 V, the device will be in the standby mode, but
the standby current will be greater. The device requires
standard access time (tCE) for read access when the
device is in either of these standby modes, before it is
ready to read data.
10
The device also enters the standby mode when the
RESET# pin is driven low. Refer to the next section,
RESET#: Hardware Reset Pin.
If the device is deselected during erasure or programming, the device draws active current until the
operation is completed.
ICC3 in the DC Characteristics table represents the
standby current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device
energy consumption. The device automatically
enables this mode when addresses remain stable for
tACC + 50 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals.
Standard address access timings provide new data
when addresses are changed. While in sleep mode,
output data is latched and always available to the
system. ICC4 in the DC Characteristics table represents
the automatic sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the
RESET# pin is driven low for at least a period of tRP, the
device immediately terminates any operation in
progress, tristates all output pins, and ignores all
read/write commands for the duration of the RESET#
pulse. The device also resets the internal state
machine to reading array data. The operation that was
interrupted should be reinitiated once the device is
ready to accept another command sequence, to
ensure data integrity.
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at VSS±0.2 V, the device
draws CMOS standby current (ICC4). If RESET# is held
at VIL but not within VSS±0.2 V, the standby current will
be greater.
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory.
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the
internal reset operation is complete, which requires a
time of tREADY (during Embedded Algorithms). The
system can thus monitor RY/BY# to determine whether
the reset operation is complete. If RESET# is asserted
when a program or erase operation is not executing
(RY/BY# pin is “1”), the reset operation is completed
within a time of tREADY (not during Embedded Algorithms). The system can read data t RH after the
RESET# pin returns to VIH.
Refer to the AC Characteristics tables for RESET#
parameters and to Figure 14 for the timing diagram.

tion, when verifying sector protection, the sector
address must appear on the appropriate highest order
address bits (see Tables 2 and 3). Table 4 shows the
remaining address bits that are don’t care. When all
necessary bits have been set as required, the programming equipment may then read the corresponding
identifier code on DQ7–DQ0.
The autoselect mode provides manufacturer and
device identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equipment
to automatically match a device to be programmed with
its corresponding programming algorithm. However,
the autoselect codes can also be accessed in-system
through the command register.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in Table 5. This method
does not require VID. See “Command Definitions” for
details on using the autoselect mode.
When using programming equipment, the autoselect
mode requires VID on address pin A9. Address pins

Sector Protection/Unprotection
The hardware sector protection feature disables both
program and erase operations in any sector. The hardware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors. Sector protection/unprotection can be implemented via two methods.
Sector Protection/ Unprotection requires VID on the
RESET# pin only, and can be implemented either insystem or via programming equipment. Figure 1 shows
the algorithms and Figure 23 shows the timing diagram. For sector unprotect, all unprotected sectors
must first be protected prior to the first sector unprotect
write cycle.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sectors at its factory prior to shipping the device
March 17, 2003
through AMD’s ExpressFlash™ Service. Contact an
AMD representative for details.
It is possible to determine whether a sector is protected
or unprotected. See “Autoselect Mode” for details.
Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the
RESET# pin to VID. During this mode, formerly protected sectors can be programmed or erased by
selecting the sector addresses. Once VID is removed
from the RESET# pin, all the previously protected
sectors are protected again. Figure 2 shows the algorithm, and Figure 22 shows the timing diagrams, for
this feature.

caused by spurious system level signals during VCC
power-up and power-down transitions, or from system
noise.
START
RESET# = VID
(Note 1)
Low VCC Write Inhibit
When V CC is less than V LKO , the device does not
accept any write cycles. This protects data during VCC
power-up and power-down. The command register and
all internal program/erase circuits are disabled, and the
device resets. Subsequent writes are ignored until VCC
is greater than VLKO . The system must provide the
proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO.

Unprotect Completed
(Note 2)
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on OE#, CE# or
WE# do not initiate a write cycle.
Logical Inhibit
Notes:
1. All protected sectors unprotected.
Write cycles are inhibited by holding any one of OE# =
VIL, CE# = VIH or WE# = VIH. To initiate a write cycle,
CE# and WE# must be a logical zero while OE# is a
logical one.
2. All previously protected sectors are protected once
again.
Figure 2.
Temporary Sector Unprotect Operation
Hardware Data Protection
The command sequence requirement of unlock cycles
for programming or erasing provides data protection
against inadvertent writes (refer to Table 5 for
Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power up, the
device does not accept commands on the rising edge
of WE#. The internal state machine is automatically
reset to reading array data on power-up.
COMMAND DEFINITIONS
Writing specific address and data commands or
sequences into the command register initiates device
operations. Table 5 defines the valid register command
sequences. Writing incorrect address and data values
or writing them in the improper sequence may place
the device in an unknown state. A reset command is
then required to return the device to reading array data.
All addresses are latched on the falling edge of WE# or
CE#, whichever happens later. All data is latched on
the rising edge of WE# or CE#, whichever happens
first. Refer to the appropriate timing diagrams in the
“AC Characteristics” section.
Reading Array Data
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data. The device is also ready to read array
data after completing an Embedded Program or
Embedded Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The
March 17, 2003
system can read array data using the standard read
timings, except that if it reads at an address within
erase-suspended sectors, the device outputs status
data. After completing a programming operation in the
Erase Suspend mode, the system may once again
read array data with the same exception. See “Erase
Suspend/Erase Resume Commands” for more information on this mode.
The system must issue the reset command to reenable the device for reading array data if DQ5 goes
high, or while in the autoselect mode. See the “Reset
Command” section, next.
See also “Requirements for Reading Array Data” in the
“Device Bus Operations” section for more information.
The Read Operations table provides the read parameters, and Figure 13 shows the timing diagram.
Reset Command
Writing the reset command to the device resets the
device to reading array data. Address bits are don’t
care for this command.
Am29SL800D
15
A D V A N C E
I N F O R M A T I O N
The reset command may be written between the
sequence cycles in an erase command sequence
before erasing begins. This resets the device to
reading array data. Once erasure begins, however, the
device ignores reset commands until the operation is
complete.
The reset command may be written between the
sequence cycles in a program command sequence
before programming begins. This resets the device to
reading array data (also applies to programming in
Erase Suspend mode). Once programming begins,
however, the device ignores reset commands until the
operation is complete.
The reset command may be written between the
sequence cycles in an autoselect command sequence.
Once in the autoselect mode, the reset command must
be written to return to reading array data (also applies
to autoselect during Erase Suspend).
If DQ5 goes high during a program or erase operation,
writing the reset command returns the device to
reading array data (also applies during Erase
Suspend).
Autoselect Command Sequence
The autoselect command sequence allows the host
system to access the manufacturer and devices codes,
and determine whether or not a sector is protected.
Table 5 shows the address and data requirements.
This method is an alternative to that shown in Table 4,
which is intended for PROM programmers and requires
VID on address bit A9.
The autoselect command sequence is initiated by
writing two unlock cycles, followed by the autoselect
command. The device then enters the autoselect
mode, and the system may read at any address any
number of times, without initiating another command
sequence. A read cycle at address XX00h retrieves the
manufacturer code. A read cycle at address 01h in
word mode (or 02h in byte mode) returns the device
code. A read cycle containing a sector address (SA)
and the address 02h in word mode (or 04h in byte
mode) returns 01h if that sector is protected, or 00h if it
is unprotected. Refer to Tables 2 and 3 for valid sector
addresses.
The system must write the reset command to exit the
autoselect mode and return to reading array data.
Word/Byte Program Command Sequence
The system may program the device by word or byte,
depending on the state of the BYTE# pin. Programming is a four-bus-cycle operation. The program
command sequence is initiated by writing two unlock
write cycles, followed by the program set-up command.
The program address and data are written next, which
in turn initiate the Embedded Program algorithm. The
16
system is not required to provide further controls or timings. The device automatically generates the program
pulses and verifies the programmed cell margin. Table
5 shows the address and data requirements for the
byte program command sequence.
When the Embedded Program algorithm is complete,
the device then returns to reading array data and
addresses are no longer latched. The system can
determine the status of the program operation by using
DQ7, DQ6, or RY/BY#. See “Write Operation Status”
for information on these status bits.
Any commands written to the device during the
Embedded Program Algorithm are ignored. Note that a
hardware reset immediately terminates the programm i ng op er a tio n. T h e B y te P ro gr am c o m ma n d
sequence should be reinitiated once the device has
reset to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across
sector boundaries. A bit cannot be programmed
from a “0” back to a “1”. Attempting to do so may halt

Polling algorithm to indicate the operation was successful. However, a succeeding read will show that the
data is still “0”. Only erase operations can convert a “0”
to a “1”.
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to
program bytes or words to the device faster than using
the standard program command sequence. The unlock
bypass command sequence is initiated by first writing
two unlock cycles. This is followed by a third write cycle
containing the unlock bypass command, 20h. The
device then enters the unlock bypass mode. A twocycle unlock bypass program command sequence is all
that is required to program in this mode. The first cycle
in this sequence contains the unlock bypass program
command, A0h; the second cycle contains the program
address and data. Additional data is programmed in
the same manner. This mode dispenses with the initial
two unlock cycles required in the standard program
command sequence, resulting in faster total programming time. Table 5 shows the requirements for the
command sequence.
During the unlock bypass mode, only the Unlock
Bypass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset
command sequence. The first cycle must contain the
data 90h; the second cycle the data 00h. Addresses
are don’t cares. The device then returns to reading
array data.

Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase
command sequence is initiated by writing two unlock
cycles, followed by a set-up command. Two additional
unlock write cycles are then followed by the chip erase
command, which in turn invokes the Embedded Erase
algorithm. The device does not require the system to
preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire
memory for an all zero data pattern prior to electrical
erase. The system is not required to provide any controls or timings during these operations. Table 5 shows
the address and data requirements for the chip erase
command sequence.

hardware reset during the chip erase operation immediately terminates the operation. The Chip Erase
command sequence should be reinitiated once the
device has returned to reading array data, to ensure
data integrity.
March 17, 2003
Sector erase is a six bus cycle operation. The sector
erase command sequence is initiated by writing two
unlock cycles, followed by a set-up command. Two
additional unlock write cycles are then followed by the
address of the sector to be erased, and the sector
erase command. Table 5 shows the address and data
requirements for the sector erase command sequence.
After the command sequence is written, a sector erase
time-out of 50 µs begins. During the time-out period,
additional sector addresses and sector erase commands may be written. Loading the sector erase buffer
may be done in any sequence, and the number of
sectors may be from one sector to all sectors. The time
between these additional cycles must be less than 50
µs, otherwise the last address and command might not
be accepted, and erasure may begin. It is recommended that processor interrupts be disabled during
this time to ensure all commands are accepted. The
interrupts can be re-enabled after the last Sector Erase
command is written. If the time between additional
sector erase commands can be assumed to be less
than 50 µs, the system need not monitor DQ3. Any
command other than Sector Erase or Erase
Suspend during the time-out period resets the
device to reading array data. The system must
rewrite the command sequence and any additional
sector addresses and commands.
The system can monitor DQ3 to determine if the sector
erase timer has timed out. (See the “DQ3: Sector
Erase Timer” section.) The time-out begins from the
rising edge of the final WE# pulse in the command
sequence.
Once the sector erase operation has begun, only the
Erase Suspend command is valid. All other commands
are ignored. Note that a hardware reset during the
sector erase operation immediately terminates the
operation. The Sector Erase command sequence

should be reinitiated once the device has returned to
reading array data, to ensure data integrity.
When the Embedded Erase algorithm is complete, the
device returns to reading array data and addresses are
no longer latched. The system can determine the
status of the erase operation by using DQ7, DQ6, DQ2,
or RY/BY#. (Refer to “Write Operation Status” for information on these status bits.)
Figure 4 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations tables in
the “AC Characteristics” section for parameters, and to
Figure 18 for timing diagrams.
Erase Suspend/Erase Resume Commands
The Erase Suspend command allows the system to
interrupt a sector erase operation and then read data
from, or program data to, any sector not selected for
erasure. This command is valid only during the sector
erase operation, including the 50 µs time-out period
during the sector erase command sequence. The
Erase Suspend command is ignored if written during
the chip erase operation or Embedded Program algorithm. Writing the Erase Suspend command during the
Sector Erase time-out immediately terminates the
time-out period and suspends the erase operation.
Addresses are “don’t-cares” when writing the Erase
Suspend command.
status of the program operation using the DQ7 or DQ6
status bits, just as in the standard program operation.
See “Write Operation Status” for more information.
The system may also write the autoselect command
sequence when the device is in the Erase Suspend
mode. The device allows reading autoselect codes
even at addresses within erasing sectors, since the
codes are not stored in the memory array. When the
device exits the autoselect mode, the device reverts to
the Erase Suspend mode, and is ready for another
valid operation. See “Autoselect Command Sequence”
for more information.
The system must write the Erase Resume command
(address bits are “don’t care”) to exit the erase suspend
mode and continue the sector erase operation. Further
writes of the Resume command are ignored. Another
Erase Suspend command can be written after the
device has resumed erasing.
START
Write Erase
Command Sequence
When the Erase Suspend command is written during a
sector erase operation, the device requires a maximum
of 20 µs to suspend the erase operation. However,
when the Erase Suspend command is written during
the sector erase time-out, the device immediately terminates the time-out period and suspends the erase
operation.
After the erase operation has been suspended, the
system can read array data from or program data to
any sector not selected for erasure. (The device “erase
suspends” all sectors selected for erasure.) Normal
read and write timings and command definitions apply.
Reading at any address within erase-suspended
sectors produces status data on DQ7–DQ0. The
system can use DQ7, or DQ6 and DQ2 together, to
determine if a sector is actively erasing or is erase-suspended. See “Write Operation Status” for information
on these status bits.

WRITE OPERATION STATUS
The device provides several bits to determine the
status of a write operation: DQ2, DQ3, DQ5, DQ6,
DQ7, and RY/BY#. Table 6 and the following subsections describe the functions of these bits. DQ7,
RY/BY#, and DQ6 each offer a method for determining
whether a program or erase operation is complete or in
progress. These three bits are discussed first.
Table 6 shows the outputs for Data# Polling on DQ7.
Figure 5 shows the Data# Polling algorithm.
START
DQ7: Data# Polling
Read DQ7–DQ0
Addr = VA
The Data# Polling bit, DQ7, indicates to the host
system whether an Embedded Algorithm is in progress
or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the
final WE# pulse in the program or erase command
sequence.
During the Embedded Program algorithm, the device
outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to
programming during Erase Suspend. When the
Embedded Program algorithm is complete, the device
outputs the datum programmed to DQ7. The system
must provide the program address to read valid status
information on DQ7. If a program address falls within a
protected sector, Data# Polling on DQ7 is active for
approximately 1 µs, then the device returns to reading
array data.
DQ7 = Data?
No
No
When the system detects DQ7 has changed from the
complement to true data, it can read valid data at DQ7–
DQ0 on the following read cycles. This is because DQ7
may change asynchronously with DQ0–DQ6 while
Output Enable (OE#) is asserted low. Figure 19, Data#
Polling Timings (During Embedded Algorithms), in the
“AC Characteristics” section illustrates this.
20
DQ5 = 1?
Yes
Read DQ7–DQ0
Addr = VA
During the Embedded Erase algorithm, Data# Polling
produces a “0” on DQ7. When the Embedded Erase
algorithm is complete, or if the device enters the Erase
Suspend mode, Data# Polling produces a “1” on DQ7.
This is analogous to the complement/true datum output
described for the Embedded Program algorithm: the
erase function changes all the bits in a sector to “1”;
prior to this, the device outputs the “complement,” or
“0.” The system must provide an address within any of
the sectors selected for erasure to read valid status
information on DQ7.
After an erase command sequence is written, if all
sectors selected for erasing are protected, Data#
Polling on DQ7 is active for approximately 100 µs, then
the device returns to reading array data. If not all
selected sectors are protected, the Embedded Erase
algorithm erases the unprotected sectors, and ignores
the selected sectors that are protected.
Yes
DQ7 = Data?
Yes
No
FAIL
PASS
Notes:
1. VA = Valid address for programming. During a sector
erase operation, a valid address is an address within any
sector selected for erasure. During chip erase, a valid
address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = “1” because
DQ7 may change simultaneously with DQ5.

I N F O R M A T I O N
RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin that
indicates whether an Embedded Algorithm is in
progress or complete. The RY/BY# status is valid after
the rising edge of the final WE# pulse in the command
sequence. Since RY/BY# is an open-drain output,
several RY/BY# pins can be tied together in parallel
with a pull-up resistor to VCC.
If the output is low (Busy), the device is actively erasing
or programming. (This includes programming in the
Erase Suspend mode.) If the output is high (Ready),
the device is ready to read array data (including during
the Erase Suspend mode), or is in the standby mode.
Table 6 shows the outputs for RY/BY#. Figures 14, 17
and 18 shows RY/BY# for reset, program, and erase
operations, respectively.
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded
Program or Erase algorithm is in progress or complete,
or whether the device has entered the Erase Suspend
mode. Toggle Bit I may be read at any address, and is
valid after the rising edge of the final WE# pulse in the
command sequence (prior to the program or erase
operation), and during the sector erase time-out.
During an Embedded Program or Erase algorithm
operation, successive read cycles to any address
cause DQ6 to toggle (The system may use either OE#
or CE# to control the read cycles). When the operation
is complete, DQ6 stops toggling.
After an erase command sequence is written, if all
sectors selected for erasing are protected, DQ6
toggles for approximately 100 µs, then returns to
reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the
unprotected sectors, and ignores the selected sectors
that are protected.
The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erasesuspended. When the device is actively erasing (that
is, the Embedded Erase algorithm is in progress), DQ6
toggles. When the device enters the Erase Suspend
mode, DQ6 stops toggling. However, the system must
also use DQ2 to determine which sectors are erasing
or erase-suspended. Alternatively, the system can use
DQ7 (see the subsection on DQ7: Data# Polling).
If a program address falls within a protected sector,
DQ6 toggles for approximately 1 µs after the program
command sequence is written, then returns to reading
array data.
DQ6 also toggles during the erase-suspend-program
mode, and stops toggling once the Embedded
Program algorithm is complete.
March 17, 2003
Table 6 shows the outputs for Toggle Bit I on DQ6.
Figure 6 shows the toggle bit algorithm. Figure 20 in the
“AC Characteristics” section shows the toggle bit timing
diagrams. Figure 21 shows the differences between
DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II.
DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing
(that is, the Embedded Erase algorithm is in progress),
or whether that sector is erase-suspended. Toggle Bit
II is valid after the rising edge of the final WE# pulse in
the command sequence. The device toggles DQ2 with
each OE# or CE# read cycle.
DQ2 toggles when the system reads at addresses
within those sectors that have been selected for erasure. But DQ2 cannot distinguish whether the sector is
actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively
erasing, or is in Erase Suspend, but cannot distinguish
which sectors are selected for erasure. Thus, both
status bits are required for sector and mode information. Refer to Table 6 to compare outputs for DQ2 and
DQ6.
Figure 6 shows the toggle bit algorithm in flowchart
form, and the section “DQ2: Toggle Bit II” explains the
algorithm. See also the DQ6: Toggle Bit I subsection.
Figure 20 shows the toggle bit timing diagram. Figure
21 shows the differences between DQ2 and DQ6 in
graphical form.
Reading Toggle Bits DQ6/DQ2
Refer to Figure 6 for the following discussion. Whenever the system initially begins reading toggle bit
status, it must read DQ7–DQ0 at least twice in a row to
determine whether a toggle bit is toggling. Typically, the
system would note and store the value of the toggle bit
after the first read. After the second read, the system
would compare the new value of the toggle bit with the
first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can
read array data on DQ7–DQ0 on the following read
cycle.
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the
system also should note whether the value of DQ5 is
high (see the section on DQ5). If it is, the system
should then determine again whether the toggle bit is
toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer
toggling, the device has successfully completed the
program or erase operation. If it is still toggling, the
device did not completed the operation successfully,
and the system must write the reset command to return
to reading array data.
Am29SL800D
21
A D V A N C E
I N F O R M A T I O N
The remaining scenario is that the system initially
determines that the toggle bit is toggling and DQ5 has
not gone high. The system may continue to monitor the
toggle bit and DQ5 through successive read cycles,
determining the status as described in the previous
paragraph. Alternatively, it may choose to perform
other system tasks. In this case, the system must start
at the beginning of the algorithm when it returns to
determine the status of the operation (top of Figure 6).
DQ5 indicates whether the program or erase time has
exceeded a specified internal pulse count limit. Under
these conditions DQ5 produces a “1.” This is a failure
condition that indicates the program or erase cycle was
not successfully completed.
START
The DQ5 failure condition may appear if the system
tries to program a “1” to a location that is previously
programmed to “0.” Only an erase operation can
change a “0” back to a “1.” Under this condition, the
device halts the operation, and when the operation has
exceeded the timing limits, DQ5 produces a “1.”
Read DQ7–DQ0
Under both these conditions, the system must issue
the reset command to return the device to reading
array data.
DQ3: Sector Erase Timer
(Note 1)
After writing a sector erase command sequence, the
system may read DQ3 to determine whether or not an
erase operation has begun. (The sector erase timer
does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire timeout also applies after each additional sector erase command. When the time-out is complete, DQ3 switches
from “0” to “1.” If the time between additional sector
erase commands from the system can be assumed to
be less than 50 µs, the system need not monitor DQ3.
See also the “Sector Erase Command Sequence”
section.

After the sector erase command sequence is written,
the system should read the status on DQ7 (Data#

accepted the command sequence, and then read DQ3.
If DQ3 is “1”, the internally controlled erase cycle has
begun; all further commands (other than Erase Suspend) are ignored until the erase operation is complete.
If DQ3 is “0”, the device will accept additional sector
erase commands. To ensure the command has been
accepted, the system software should check the status
of DQ3 prior to and following each subsequent sector
erase command. If DQ3 is high on the second status
check, the last command might not have been
accepted. Table 6 shows the outputs for DQ3.

Comments
Excludes 00h programming

Excludes system level
overhead (Note 5)
Notes:
1. Typical program and erase times assume the following conditions: 25°C, 2.0 V VCC, 1,000,000 cycles. Additionally,
programming typicals assume checkerboard pattern.
2. Under worst case conditions of 90°C, VCC = 1.8 V, 1,000,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
program faster than the maximum program times listed.
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See
Table 5 for further information on command definitions.
6. The device has a minimum guaranteed erase and program cycle endurance of 1,000,000 cycles.
