MX30UF1G16(18)AC
PIN FUNCTIONS
ADDRESS LATCH ENABLE: ALE
The MX30UF1G16(18)AC device is a sequential
access memory that utilizes multiplexing input of
Command/Address/Data.
The ALE controls the address input. When the ALE
goes high, the address is latched at the rising edge
of WE#.
I/O PORT: IOx - IO0
WRITE PROTECT: WP#
The IOx to IO0 pins are for address/command
input and data output to/from the device. IO7-IO0
pins are for x8 device, IO15-IO0 pins are for x16
device.
The WP# signal keeps low and then the memory will
not accept the program/erase operation. It is recommended to keep WP# pin low during power on/off
sequence. Please refer to the waveform of "Power
On/Off Sequence".
CHIP ENABLE: CE#
The device goes into low-power Standby Mode
when CE# goes high during a read operation and
not at busy stage.
READY/Busy: R/B#
The R/B# is an open-drain output pin. The R/B#
outputs the ready/busy status of read/program/
erase operation of the device. When the R/B# is at
low, the device is busy for read or program or erase
operation. When the R/B# is at high, the read/
program/erase operation is finished.
The CE# goes low to enable the device to be
ready for standard operation. When the CE# goes
high, the device is deselected. However, when the
device is at busy stage, the device will not go to
standby mode when CE# pin goes high.
Please refer to Section 9-1 for details.
READ ENABLE: RE#
PROTECTION: PT
The RE# (Read Enable) allows the data to be
output by a tREA time after the falling edge of
RE#. The internal address counter is automatically
increased by one at the falling edge of RE#.
The PT pin is the hardware method to protect the
whole chip from program/erase operation. When
the PT pin is at high at power-on, the whole chip is
protected even the WP# is at high; the un-protect
command and procedure is necessary before
any program/erase operation. When the PT pin is
connected to low or floating, the Protection function
is disabled.
WRITE ENABLE: WE#
When the WE# goes low, the address/data/
command are latched at the rising edge of WE#.
Please refer to Section - Block Protection for
details.
COMMAND LATCH ENABLE: CLE
The CLE controls the command input. When the
CLE goes high, the command data is latched at
the rising edge of the WE#.

6-2. Page Read
The MX30UF1G16(18)AC array is accessed in Page of 2,112 bytes or 1,056 words. External reads begins
after the R/B# pin goes to READY.
The Read operation may also be initiated by writing the 00h command and giving the address (column
and row address) and being confirmed by the 30h command, the device begins the internal read operation
and the chip enters busy state. The data can be read out in sequence after the chip is ready. Refer to the
waveform for Read Operation as below.
If the host side uses a sequential access time (tRC) of less than 30ns, the data can be latched on the next
falling edge of RE# as the waveform of EDO mode (Figure 9-2).
To access the data in the same page randomly, a command of 05h may be written and only column address
following and then confirmed by E0h command.

6-3. Cache Read Sequential
The cache read sequential operation is for throughput enhancement by using the internal cache buffer. It
allows the consecutive pages to be read-out without giving next page address, which reduces the latency
time from tR to tRCBSY between pages or blocks. While the data is read out on one page, the data of next
page can be read into the cache buffer.
After writing the 00h command, the column and row address should be given for the start page selection,
and followed by the 30h command for address confirmation. After that, the CACHE READ operation starts
after a latency time tR and following a 31h command with the latency time of tRCBSY, the data can be readout sequentially from 1st column address (A[11:0]=000h for x8; A[10:0]=000h for x16) without giving next
page address input. The 31h command is necessary to confirm the next cache read sequential operation and
followed by a tRCBSY latency time before next page data is necessary. The CACHE READ SEQUENTIAL
command is also valid for the consecutive page cross block.
The random data out (05h-E0h) command set is available to change the column address of the current page
data in the cache register.
The user can check the chip status by the following method:
- R/B# pin ("0" means the data is not ready, "1" means the user can read the data)
- Status Register (SR[6] functions the same as R/B# pin, SR[5] indicates the internal chip operation, "0"
means the chip is in internal operation and "1" means the chip is idle.) Status Register can be checked
after the Read Status command (70h) is issued. Command 00h should be given to return to the cache read
sequential operation.
To confirm the last page to be read-out during the cache read sequential operation, a 3Fh command is
needed to replace the 31h command prior to the last data-out.

6-4. Cache Read Random
The main difference from the Cache Read Sequential operation is the Cache Read Random operation may
allow the random page to be read-out with cache operation not just for the consecutive page only.
After writing the 00h command, the column and row address should be given for the start page selection,
and followed by the 30h command for address confirmation. The column address is ignored in the cache
read random operation. And then, the CACHE READ RANDOM operation starts after a latency time tR and
following a 00h command with the selected page address and following a 31h command, the data can be
read-out sequentially from 1st column address (A[11:0]=000h for x8; A[10:0]=000h for x16) after the latency
time of tRCBSY. After the previous selected page data out, a new selected page address can be given
by writing the 00h-31h command set again. The CACHE READ RANDOM command is also valid for the
consecutive page cross block.
The random data out (05h-E0h) command set is available to change the column address of the current page
data in the cache register.
The user can check the chip status by the following method:
- R/B# pin ("0" means the data is not ready, "1" means the user can read the data)
- Status Register can be checked after the Read Status command (70h) is issued. (SR[6] behaves the same
as R/B# pin, SR[5] indicates the internal chip operation, "0" means the chip is in internal operation and "1"
means the chip is idle.) Command 00h should be given to return to the cache read operation.
To confirm the last page to be read-out during the cache read operation, a 3Fh command is needed to replace
the 31h command prior to the last data-out.

6-5. Page Program
The memory is programmed by page, which is 2,112 bytes, or 1056 words. After Program load command
(80h) is issued and the row and column address is given, the data will be loaded into the chip sequentially.
Random Data Input command (85h) allows multi-data load in non-sequential address. After data load is
complete, program confirm command (10h) is issued to start the page program operation. The page program
operation in a block should start from the low address to high address. Partial program in a page is allowed
up to 4 times. However, the random data input mode for programming a page is allowed and number of times
is not limited.
The status of the program completion can be detected by R/B# pin or Status register bit SR[6].
The program result is shown in the chip status bit (SR[0]). SR[0] = 1 indicates the Page Program is not
successful and SR[0] = 0 means the program operation is successful.
During the Page Program progressing, only the read status register command and reset command are
accepted, others are ignored.

6-6. Cache Program
The cache program feature enhances the program performance by using the cache buffer of 2,112-byte or
1,056 words. The serial data can be input to the cache buffer while the previous data stored in the buffer are
programming into the memory cell. Cache Program command sequence is almost the same as page program
command sequence. Only the Program Confirm command (10h) is replaced by cache Program command (15h).
After the Cache Program command (15h) is issued. The user can check the status by the following methods.
- R/B# pin
- Cache Status Bit (SR[6] = 0 indicates the cache is busy; SR[6] = 1 means the cache is ready).
The user can issue another Cache Program Command Sequence after the Cache is ready. The user can
always monitor the chip state by Ready/Busy Status Bit (SR[5]). The user can issues either program confirm
command (10h) or cache program command (15h) for the last page if the user monitor the chip status by
issuing Read Status Command (70h).
However, if the user only monitors the R/B# pin, the user needs to issue the program confirm command (10h)
for the last page.
The user can check the Pass/Fail Status through P/F Status Bit (SR[0]) and Cache P/F Status Bit (SR[1]).
SR[1] represents Pass/Fail Status of the previous page. SR[1] is updated when SR[6] change from 0 to 1 or
Chip is ready. SR[0] shows the Pass/Fail status of the current page. It is updated when SR[5] change from "0"
to "1" or the end of the internal programming. For more details, please refer to the related waveforms.

This device supports a block erase command. This command will erase a block of 64 pages associated with
the most significant address bits.
The completion of the erase operation can be detected by R/B# pin or Status register bit (IO6). Recommend
to check the status register bit IO0 after the erase operation completes.
During the erasing process, only the read status register command and reset command can be accepted,
others are ignored.

6-9. Status Read
The MX30UF1G16(18)AC provides a status register that outputs the device status by writing a command
code 70h, and then the IO pins output the status at the falling edge of CE# or RE# which occurs last. Even
though when multiple flash devices are connecting in system and the R/B#pins are common-wired, the two
lines of CE# and RE# may be checked for individual devices status separately.
The status read command 70h will keep the device at the status read mode unless next valid command is
issued. The resulting information is outlined in Table 4 as below.

The reset command FFh resets the read/program/erase operation and clear the status register to be E0h after
chip returns to ready state (when WP# is high). The reset command during the program/erase operation will
result in the content of the selected locations(perform programming/erasing) might be partially programmed/
erased.
If the Flash memory has already been set to reset stage with reset command, the additional new reset
command is invalid.

6-11. Parameter Page Read (ONFI)
The NAND Flash device support ONFI Parameter Page Read and the parameter can be read out by sending
the command of ECh and giving the address 00h. The NAND device information may refer to the table of
parameter page(ONFI), there are three copies of 256-byte data and additional redundant parameter pages.
Once sending the ECh command, the NAND device will remain in the Parameter Page Read mode until next
valid command is sent.
The Random Data Out command set (05h-E0h) can be used to change the parameter location for the specific
parameter data random read out.
The Status Read command (70h) can be used to check the completion with a following read command (00h)
to enable the data out.

Note: The Integrity CRC (Cycling Redundancy Check) field is used to verify that the contents of the
parameters page were transferred correctly to the host. Please refer to ONFI 1.0 specifications for
details.
The CRC shall be calculated using the following 16-bit generator polynomial:
G(X) = X16 + X15 +X2 + 1
6-12. Unique ID Read (ONFI)
The unique ID is 32-byte and with 16 copies for back-up purpose. After writing the Unique ID read command
(EDh) and following the one address byte (00h), the host may read out the unique ID data. The host need to
XOR the 1st 16-byte unique data and the 2nd 16-byte complement data to get the result, if the result is FFh,
the unique ID data is correct; otherwise, host need to repeat the XOR with the next copy of Unique ID data.
Once sending the EDh command, the NAND device will remain in the Unique ID read mode until next valid
command is sent.
To change the data output location, it is recommended to use the Random Data Out command set (05h-E0h).
The Status Read command (70h) can be used to check the completion. To continue the read operation, a
following read command (00h) to re-enable the data out is necessary.

6-13. Feature Set Operation (ONFI)
The Feature Set operation is to change the default power-on feature sets by using the Set Feature and Get
Feature command and writing the specific parameter data (P1-P4) on the specific feature addresses. The
NAND device may remain the current feature set until next power cycle since the feature set data is volatile.
However, the reset command (FFh) can not reset the current feature set.

6-13-3.Secure OTP (One-Time-Programmable) Feature
There is an OTP area which has thirty full pages (30 x 2,112-byte) guarantee to be good for system
device serial number storage or other fixed code storage. The OTP area is a non-erasable and one-timeprogrammable area, which is default to “1” and allows whole page or partial page program to be “0”, once the
OTP protection mode is set, the OTP area becomes read-only and cannot be programmed again.
The OTP operation is operated by the Set Feature/ Get Feature operation to access the OTP operation mode
and OTP protection mode.
To check the NAND device is ready or busy in the OTP operation mode, either checking the R/B# or writing
the Status Read command (70h) may collect the status.
To exit the OTP operation or protect mode, it can be done by writing 00h to P1 at feature address 90h.
OTP Read/Program Operation
To enter the OTP operation mode, it is by using the Set Feature command (EFh) and followed by the feature
address (90h) and then input the 01h to P1 and 00h to P2-P4 of sub-Feature Parameter data( please refer to
the sub-Feature Parameter table). After enter the OTP operation mode, the normal Read command (00h-30h)
or Page program( 80h-10h) command can be used to read the OTP area or program it. The address of OTP
is located on the 02h-1Fh of page address.
Besides the normal Read command, the Random Data Output command (05h-E0h) can be used for read
OTP data. However, the Cache Read command is not supported in the OTP area.
Besides the normal page program command, the Random Data Input command (85h) allows multi-data load
in non-sequential address. After data load is completed, a program confirm command (10h) is issued to start
the page program operation. The number of partial-page OTP program is 8 per each OTP page.

OTP Protection Operation
To prevent the further OTP data to be changed, the OTP protection mode operation is necessary. To enter the
OTP protection mode, it can be done by using the Set Feature command (EFh) and followed by the feature
address (90h) and then input the 03h to P1 and 00h to P2-P4 of sub-Feature Parameter data (please refer to
the sub-Feature Parameter table). And then the normal page program command (80h-10h) with the address
00h before the 10h command is required.
The OTP Protection mode is operated by the whole OTP area instead of individual OTP page. Once the OTP
protection mode is set, the OTP area cannot be programmed or unprotected again.

6-13-4.Block Protection
The block protect operation can protect the whole chip or selected blocks from erasing or programming. Through
the PT pin at power-on stage, it decides the block protection operation is enabled or disabled. At power-on, if the
PT pin is connected to high, the block protection operation is enabled, all the blocks are default to be protected from
programming/erasing even the WP# is disabled. If the PT pin is low, block protection operation is disabled. Please
refer to the Figure 32. PT Pin and Block Protection Mode Operation.
When program or erase attempt at a protected block is happened, the R/B# keeps low for the time of tPBSY, and the
Status Read command (70h) may get the 60h result.
There are Temporary Protection/un-Protection and Solid Protection features as below description.
Temporary Protection/un-Protection
At power-on, if the PT pin is connected to high, all the blocks are default to be protected for the BPx protection bits are
all “1”. The Set feature command with feature address A0h followed by the destined protection bits data is necessary
to un-protect those selected blocks before those selected blocks to be updated. The WP# pin needs to connect to
high before writing the Set Feature command for the block protection operation. After the selected blocks are unprotected, those un-protected blocks can be protected again by Block Protection procedure if required.
Solid Protection
The “solid-protection” feature can be set by writing the Set Feature command with address A0h and the “SP” solidprotection bit as “1”, after that, the selected block is solid-protected and cannot be up-protected until next power cycle.

8-1. R/B#: Termination for The Ready/Busy# Pin (R/B#)
The R/B# is an open-drain output pin and a pull-up resistor is necessary to add on the R/B# pin. The R/B#
outputs the ready/busy status of read/program/ erase operation of the device. When the R/B# is at low, the
device is busy for read or program or erase operation. When the R/B# is at high, the read/program/erase
operation is finished.
Rp Value Guidence
The rise time of the R/B# signal depends on the combination of Rp and capacitive loading of the R/B# circuit.
It is approximately two times constants (Tc) between the 10% and 90% points on the R/B# waveform.
TC = R × C
Where R = Rp (Resistance of pull-up resistor), and C = CL (Total capacitive load)
The fall time of the R/B# signal majorly depends on the output impedance of the R/B# signal and the total
load capacitance.
Rp (Min.) =
Vcc (Max.) - VOL (Max.)
IOL+ΣIL
Notes:
1. Considering of the variation of device-by-device, the above data is for reference to decide the resistor value.
2. Rp maximum value depends on the maximum permissible limit of tr.
3. IL is the total sum of the input currents of all devices tied to the R/B pin.

9. SOFTWARE ALGORITHM
9-1. Invalid Blocks (Bad Blocks)
The bad blocks are included in the device while it gets shipped. During the time of using the device, the
additional bad blocks might be increasing; therefore, it is recommended to check the bad block marks
and avoid using the bad blocks. Furthermore, please read out the bad block information before any erase
operation since it may be cleared by any erase operation.
Figure 36. Bad Blocks
Bad Block
Bad Block
While the device is shipped, the value of all data bytes of the good blocks are FFh. The 1st byte of the 1st
and 2nd page in the spare area for bad block will be 00h for x8; and 0000h for x16. The erase operation at
the bad blocks is not recommended.
After the device is installed in the system, the bad block checking is recommended. The figure shows the brief
test flow by the system software managing the bad blocks while the bad blocks were found. When a block
gets damaged, it should not be used any more.
Due to the blocks are isolated from bit-line by the selected gate, the performance of good blocks will not be
impacted by bad ones.

9-2. Bad Block Test Flow
Although the initial bad blocks are marked by the flash vendor, they could be inadvertently erased and
destroyed by a user that does not pay attention to them. To prevent this from occurring, it is necessary to
always know where any bad blocks are located. Continually checking for bad block markers during normal
use would be very time consuming, so it is highly recommended to initially locate all bad blocks and build a
bad block table and reference it during normal NAND flash use. This will prevent having the initial bad block
markers erased by an unexpected program or erase operation. Failure to keep track of bad blocks can be
fatal for the application. For example, if boot code is programmed into a bad block, a boot up failure may
occur. The following section shows the recommended flow for creating a bad block table.
