GENERAL DESCRIPTION
The Am30LV0064D is a 64 Mbit mass storage Flash
memory device, organized as 8 Kbyte (+256 byte)
blocks (1,024 blocks total), each with 16 pages of 512
(+16) bytes (16,384 pages total).
The device is suited to high-density applications in
which data is sequential and requires frequent, fast
write capability. The UltraNAND™ block and page architecture is capable of accommodating applications
requiring IDE disk drive-compatible blocks.
Each device requires only a single 3.0 volt power
supply for read, program, and erase functions. Internally generated and regulated voltages are provided
for program and erase operations. A VCCQ pin is provided to allow 5 volts to be applied to the output buffer
logic. With 5 volt tolerant inputs, the VCCQ pin provides
the Flash device with 5 volt tolerant I/O.
The Am30LV0064D is entirely command set compatible with industry standard NAND instructions and
timing. Commands are written to the command register through the 8-bit I/O bus using standard NAND
write timing. Register contents serve as inputs to an
internal state-machine that controls the read, erase,
and programming circuitry. Write cycles also internally
latch addresses and data needed for the read, programming, and erase operations. Reading data out of the
device is similar to reading from NAND Flash devices. The
device has an initial page read access time of 7 µs, with
subsequent byte accesses of less than 50 ns per byte.
Device programming occurs on a page basis by executing the Input Data and Program Data command
sequences. This initiates the Embedded Program al-
4
gorithm—an internal algorithm that automatically times
the program pulse widths and verifies proper cell margin.
Device erasure is performed on a block basis and occurs
by executing the Block Erase command sequence. This
initiates the Embedded Erase algorithm—an internal
algorithm that automatically executes the erase operation.
During erase, the device automatically times the erase
pulse widths and verifies proper cell margin. The
block erase architecture allows memory blocks to be
erased and reprogrammed without affecting the data
contents of other blocks. The Erase Suspend/Erase
Resume feature enables the user to put erase on hold
for any period of time to read data from, or program
data to, any block that is not selected for erasure. True
background erase can thus be achieved. The device is
fully erased when shipped from the factory.
The host system can detect whether a sequential read,
program, or Block Erase operation is complete by observing the RY/BY# pin or by reading the status
register. After a program or erase cycle has been completed, the device is ready to accept another command.
Hardware data protection is provided by a write protect (WP#) input pin which inhibits all program and
erase operations when asserted (low).
The device offers a standby mode as a power-saving
feature. Once the system places the device into the
standby mode power consumption is greatly reduced.
AMD’s Flash technology combines years of Flash
memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness.

FUNCTIONAL PIN DESCRIPTION
Input/Output Pins (I/O7–I/O0)
The eight I/O pins are used to send commands, addresses, and data to the device, and to receive data
during read operations.
Command Latch Enable (CLE)
The CLE input controls activation of the command register for the receipt of commands. When CLE is high,
the command is latched into the command register on
the rising edge of the Write Enable (WE#) signal.
Address Latch Enable (ALE)
The ALE input controls activation of the address register
during the address latch operation, or the data register
during the Input Data operation. When ALE is high, the
address information is latched on the rising edge of
the Write Enable (WE#) signal. When ALE is low (and
the CLE input is low) the Input Data information is
latched on the rising edge of the Write Enable (WE#)
signal. ALE must remain high for the entire address
sequence or device will reset.
Chip Enable (CE#)
The CE# input controls the active/standby mode during command, data, and address inputs. During the
command and address latch operations, CE# must be
low prior to the falling edge of Write Enable (WE#).
During Input Data operations, CE# must remain low
until after the rising edge of WE# during the final Data
In operation. When CE# is high, and an internal operation is not in process, the device goes into standby
mode and current consumption is greatly reduced.
The CE# signal is ignored during program or erase operation, as indicated by the Busy state (RY/BY# =
low).
Read Enable (RE#)
The RE# input controls the serial data output and status from the I/O lines. The data output is triggered on
the falling edge of RE#, with valid data available after
a delay of tREA. The Status output data is also triggered
on the falling edge of RE#, with the status available
after a delay of tRLS.
Write Enable (WE#)
The WE# input is used to control the Data/Command
on the I/O lines during write operations. The I/O lines
are latched on the rising edge of the WE# signal.
Write Protect (WP#)
The WP# input provides protection from inadvertent
program/erase commands. The internal voltage regulator is reset when WP# is low, thereby preventing any
program or erase operations from occurring.
10
The WP# input should be kept low (V I L ) during
p o w e r - u p u n t i l V C C i s a b o ve V C C - m i n . D u r i n g
power-down WP# should be driven low (V IL) before
VCC is below VCC-min.
Spare Area Enable (SE#)
The SE# input controls access to the 16 bytes of spare
area on each page. When SE# is not asserted (high),
the spare area for the selected page is not enabled,
and all input or output data is directed towards the primary 512 byte storage space. When SE# is asserted
(low), access to the spare area is enabled, and data
can be transferred to or from the 16 bytes of spare
area for the appropriate page as needed. With SE#
asserted (low) information can still be transferred to or
from the 512 byte main Flash page, but when the end
of the page is reached (byte 511) the device will automatically begin transferring information to or from the
spare area.
During the Read Spare Area command sequence
(50h) the SE# input must be asserted (low) during the
command phase (CLE high). In all other cases when
the spare area is to be accessed, the SE# input must
be asserted (low) at least two access cycles prior to
the spare area access. This would require the SE#
input to be low by the time byte address 510 is selected, and SE# must remain low during the entire
period that the spare area is accessed.
Ready/Busy Output (RY/BY#)
The RY/BY# output indicates the operation status of the
device. When RY/BY# is high, the device is ready to
accept the next operation. When RY/BY# is low, an internal
program, erase, or random read operation is in progress.
RY/BY# is an open drain output pin which allows multiple RY/BY# pins to be wire-ORed together. The
RY/BY# output pin requires an external pull-up resistor
to VCC (or VCCQ) for proper operation.
Device Power Supply (VCC)
The minimum VCC operating voltage for the
Am30LV0064D is 2.7 volts. The device has an operating voltage range from 2.7 volts to 3.6 volts.
Output Buffer Power Supply (VCCQ)
The output voltage generated on the device is determined based on the VCCQ power supply input level. A
VCCQ of 2.7 to 3.6 volts will allow the device to function
as a 3.0 Volt-only device. A VCCQ of 4.5 to 5.5 volts
provides 5 volt I/O tolerance.
All input only signals are 5 volt tolerant by design, independent of the voltage on VCCQ.
Ground (VSS)
The VSS pins on the device must be grounded.

DEVICE BUS OPERATIONS, COMMAND
SET, AND COMMAND DEFINITIONS
This section describes the requirements and use of
the device bus operations, the command set, and the
command definitions. The device bus operations are
initiated through the internal command register which
decodes the command to determine the current operation to be performed. The command register itself
does not occupy any addressable memory location.
The register is composed of latches that store the

Operation
commands, along with the address and data information needed to execute the command. The contents of
the register serve as inputs to the internal state machine whose outputs dictate the function of the device.
Table 2 lists the device bus operations including the inputs and control levels they require, and the resulting
output. Table 3 lists the command set, and Table 4 lists
the command definitions. The “Device Operations”

DEVICE OPERATIONS
When the AMD Mass Storage Flash device powers
up, the command decoder is initialized to a wait for
command state. In order to perform any function, the
device must be programmed for the desired operation.
Specific commands must be issued to the device to
select one of the read modes, to input or program
data, to perform one of the block erase functions, or to
reset the device.
There are a number of commands available for reading information from the UltraNAND Flash device.
These include Read Data to read out of the Flash array, Gapless Read to read data in a special high
performance mode, Read Spare Area to read the 16
byte spare area in each page, Read ID to determine
the manufacturer and device ID, and Read Status to
check the device status.
Programming data into the Flash array is a two step
process and requires that two separate command sequences be performed. The data to be programmed
must first be loaded into the Data Registers using the
Input Data command sequence. After the data is
loaded the Page Program command is performed to
transfer the information from the Data Registers to the
Flash array.
Device erasure occurs on an 8 Kbyte block basis, with
each block in the device containing 16 pages and the
respective spare area for each page. During block
erase, the Flash device supports erase suspend and
erase resume to allow time critical tasks to be performed. These time critical tasks can be to read or
program in a block that is not currently selected for
erasure.
The Flash device also supports a reset command sequence to reset the device and return it to the wait for
command state.
All of the commands and their functions supported by
the Flash device are described in the following
sub-sections with simplified timing diagrams included.
The timing diagrams are intended to illustrate the relationship of each of the control, status, and data signals
for each of the command sequences. Please refer to
the AC/DC Characteristics section for more complete
timing information.
In each of the simplified timing diagrams, the polling
period during device busy (RY/BY# = V IL ) is not
shown. During device busy the system can poll the device internal status register or monitor the RY/BY# pin
to determine when the internal operation is complete.
Am30LV0064D

Read Operations
Read Data (00h / 01h)
There are two commands available for reading from
the Flash array (via the Data Registers). These are
Read Data—(starting with the) First Half Page (00h)
and Read Data—(starting with the) Second Half Page
(01h).
The commands are identical except for the starting region within the selected page. After the command
cycle, three address cycles are used to input the starting address for the read operation. Upon the rising
edge of the final WE# pulse there is a 7 µs latency in
which 528 bytes of information are transferred from
the Flash array page to the 528 byte Data Register.
During the 7 µs latency period the Flash device will appear busy and either the RY/BY# signal or the status
register may be used to monitor the completion of the
data transfer. Only the Reset and Read Status commands are valid during the period that the device is
busy. Once the information has been loaded into the
Data Register, it may be sequentially read with consecutive 50 ns RE# pulses. Each RE# pulse will
automatically advance the column address by one.
Once the last column has been read, the page address
will automatically increment by one and the Data Register will be updated with information from the new page
after a 7 µs latency period.
During the sequential read mode, if the Spare Area
Enable input (SE#) is high, the column address will advance to address 511 and then the page address will
increment by one. If the SE# input is low, the column
address will advance to address 527 before the page
address is incremented. This allows information in the
Spare Area to be read at the end of the page before
the next page of information is transferred into the
Data Registers. In the case of the Read Data command, the SE# input may go low anytime from before
the command is issued to before address 510 is accessed. This allows the Flash internal logic to correctly
enable the Spare Area for reading.

Gapless Read (02h) (Superset Command)
Each RE# pulse will automatically advance the column
address by one. Once the last column has been read,
the page address will automatically increment by one
and the Data Register will be updated with the new
page.
The Gapless Read command is almost identical to the
Read Data command, except that it allows reading
from multiple pages with only one 7 µs latency occurring on the first page transfer. After the command
cycle is used to write the Gapless Read op-code to the
device, three address cycles are used to input the
starting address for the Gapless Read operation.
In the case of the Gapless Read, there is no 7 µs latency period encountered when moving from the
current page to the next sequential page.
The Gapless Read operation requires that the address
entered specifies an address location in the first half of
the selected page. Upon the rising edge of the final
WE# pulse there is a 7 µs latency in which 528 bytes
of information are transferred from the Flash array
page to the 528 byte Data Register. During this 7 µs
period the device will appear busy and either the
RY/BY# signal or the status register may be used to
monitor the completion of the data transfer. Only the
Reset and Read Status commands are valid during
the period that the device is busy. Once the information has been loaded into the Data Register, it may be
sequentially read with consecutive 50 ns RE# pulses.
During the sequential read mode, if the Spare Area
Enable input (SE#) is high, the column address will advance to address 511 and then the page address will
increment by one. If the SE# input is low, the column
address will advance to address 527 before the page
address is incremented. This allows information in the
Spare Area to be read at the end of the page before
the next page of information is transferred into the
Data Registers.
This is an AMD superset command which is not available on competitive devices in the marketplace.

Read Spare Area (50h)
The Read Spare Area command is similar to the Read
Data command, except that it only reads information
from the selected page 16 byte Spare Area (address
locations 512 through 527). After the command cycle
is used to write the Read Spare Area op-code to the
device, three address cycles are used to input the
starting address for the read operation. During the
Read Spare Area command cycle the SE# input must
be low.
Because the Read Spare Area operation only reads
the 16 byte spare area in the page, address bits
A7–A4 are don’t care. Address bits A22–A9 are used
to select the Page, and address bits A3–A0 are used
to select the starting byte within the Spare Area of the
Page. Upon the rising edge of the final WE# pulse
there is a 7 µs latency in which all 528 bytes of information are transferred from the Flash array page to
the 528 byte Data Register. Following the data transfer
the internal address pointer will point to the byte selected in the Spare Area. During the 7 µs data transfer
period the device will appear busy and the RY/BY#
signal or the status register may be used to monitor
the completion of the data transfer. Only the Reset and
Read Status commands are valid during the period
that the device is busy. Once the information has been
loaded into the Data Register, the Spare Area information may be sequentially read with consecutive 50 ns
RE# pulses. Each RE# pulse will automatically advance the Spare Area column address by one. Once
the last column has been read, the page address will
automatically increment by one and the Data Register
will be updated with the new page after a 7 µs latency.
During the sequential read mode, the Spare Area Enable input (SE#) must be low. This is necessary any
time the Spare Area is being read. In this operation,
the column address will advance from the selected
starting byte location to address 527 before the page
address is incremented. After the next page of information is transferred to the Data Register, sequential
read operations will begin in the Data Register at address location 512. Unlike the Read Data and Gapless
Read modes, the Read Spare Area operation requires
that the SE# input be asserted low prior to the command being issued to the device.

The Read Status operation is used to read the device

polled to determine their specific status.

Program Operations
Input Data (80h)
The Input Data command sequence is the first of two
operations that must be performed to program information into one of the Flash pages. The second
operation, Page Program, is used to transfer information from the Data Registers to the Flash array after
20
Read Status
the Input Data procedure loads the Data Registers. In
order to set the starting region within the Data Registers (first half, second half, or Spare Area), the
appropriate command (00h, 01h, 50h) should be iss u e d p r i o r t o t h e I n p u t D a ta c o m m a n d b e i n g
performed. If a command is not submitted to assign
the starting region, the starting region will be determined by its previous state.
Am30LV0064D
After the command cycle, three address cycles are
used to input the starting address for the Input Data
operation. Upon the rising edge of the final WE# pulse,
between 1 and 528 bytes of information can be loaded
into the Data Register with consecutive 50 ns WE#
pulses. Each WE# pulse will automatically advance
the Data Register address pointer by one. If additional
write pulses are issued after the last address has been
written (511 if SE# is high or 527 if SE# is low), the
Data Register address pointer will wrap around to 0. If
additional WE# pulses are issued, the device will continue to store information into the Data Register until a
new command is issued.
The Spare Area Enable input (SE#) must be low by
the time address 510 is accessed in order to load information into the last 16 bytes of the Data Register. If
the SE# input is high, the Data Register address will
advance to address 511. If the SE# input is low, the
column address will advance to address 527. This allows information that needs to be programmed into the
Spare Area of the page to be loaded into the Data Registers properly. Please refer to Figure 8 for the simplified
timing diagram for Input Data and Page Program.
Page Program (10h)
The Page Program command sequence is issued after
the Input Data operation has loaded the proper data in
the Data Registers. Upon the rising edge of the command
cycle WE# pulse, this operation typically transfers in-
formation from the Data Registers to the Flash array in
200 µs or less, and the Flash device will appear busy
during the data transfer operation. The RY/BY# signal
or the status register may be used to monitor completion of the data transfer. Only the Reset and Read
Status commands are valid during the period that the
device is busy.
Only those bytes loaded with the Input Data command
sequence will be programmed in the Flash array. This
allows partial page programming to be performed as
needed. If no bytes were loaded into the Data Register, or if the Page Program command is issued without
the Input Data command being performed, no program
operation will occur. Unless ECC has been implemented, a given page may not be reprogrammed
without an intervening erase operation being performed on the block that contains that page. After
programming a page, the status register bit I/O0
should be checked to verify that the program operation
completed properly.
The Spare Area Enable input (SE#) must be low in
order to program information into the last 16 bytes of
the page that is selected for programming. If the SE#
input is high, the Spare Area will not be programmed.

Erase Operations
second command cycle, the Flash device will begin
the Block Erase operation.
Block Erase (60h) (D0h)
The Block Erase command sequence is a two command operation procedure that must be performed to
erase information in one of the 16 page Flash blocks.
After the first command cycle, two address cycles are
used to input the block address for the block to be
erased. Since the block address only requires address
bits A22–A13 to determine the block address, bits
A12–A9 are don’t care. After the two address cycles
are complete, the second command cycle is issued.
Upon the rising edge of the final WE# pulse for the
A block typically erases in the Flash array in 2 ms or
less and is guaranteed to erase within 10 ms. The
Flash device appears busy during the Block Erase operation and either the RY/BY# signal or the status
register may be used to monitor completion of the
erase. Only the Erase Suspend, Reset, and Read Status commands are valid during the period that the device
is busy.
After erasing a block, the status register bit I/O0
should be checked to verify that the erase operation
completed properly. Figure 10 shows the simplified
timing for Block Erase.

Erase Suspend (B0h) (Superset Command)
The Erase Suspend command sequence is only valid
during a Block Erase operation. Upon the rising edge
of the command WE# pulse, the Flash device will suspend the Block Erase operation. Either the RY/BY#
signal or the status register may be used to determine
when the Block Erase has actually been suspended.
Once the Erase Suspend has taken effect, read or
program operations may be performed in blocks that
are not selected for erasure.
Once a Block Erase has been suspended, the suspended Block Erase operation must be completed
before another block can be selected for erasure.
Block Erase
When the Erase Suspend command is issued, the
Block Erase command is inhibited. The Block Erase
will be invalid until an Erase Resume command allows
the suspended erase to complete, the device is reset,
or power is removed from the device. Refer to Figure
11 for a simplified timing diagram showing the sequence of events required to implement Erase
Suspend during a block erase operation. This is an
AMD superset command which is not available on
competitive devices in the marketplace.
Erase Resume (D0h) (Superset Command)
The Erase Resume command sequence is only valid
during an Erase Suspend operation. Upon the rising
Am30LV0064D

edge of the command WE# pulse, the Flash device
will resume the Block Erase operation that was suspended. Either the RY/BY# signal or the status register
may be used to determine when the Block Erase
completes.
After the block finishes the erase operation, the status
register bit I/O0 should be checked to verify that the
erase completed properly. Figure 11 is a simplified timing
diagram that describes how to execute an Erase Resume operation during Erase Suspend to allow the
previously suspended block erase to complete. This is
an AMD superset command which is not available on
competitive devices in the marketplace.

place on the rising edge of the command cycle WE#
pulse. If the WP# input is high, not protected, the Status Register will be set to C0h.
If a second Reset command is issued while a reset is
in process, the second Reset command will be ignored. If a Reset command is issued during a program
or erase operation, the internal high voltages will be
discharged before the device indicates that it is ready
