GENERAL DESCRIPTIONS The MX30LFxGE8AB is a 1Gb to 4Gb SLC NAND Flash memory device. Its standard NAND Flash features and reliable quality make it most suitable for embedded system code and data storage. The product family does not require the host controller to support ECC since there is an internal ECC logic inside the Flash device for the error correction and detection. The MX30LFxGE8AB is typically accessed in pages of 2,112 bytes both for read and for program operations. The MX30LFxGE8AB array is organized as thousands of blocks, which is composed by 64 pages of (2,048+64) bytes in two NAND strings structure with 32 serial connected cells in each string. Each page has an additional 64 bytes for bad block marks and other purposes. The device has an on-chip buffer of 2,112 bytes for data load and access. The MX30LFxGE8AB power consumption is 30mA during all modes of operations (Read/Program/Erase), and 50uA in standby mode. Figure 1.

The ALE controls the address input. When the ALE goes high, the address is latched at the rising edge of WE#. I/O PORT: IO7- IO0 WRITE PROTECT: WP# The IO7 to IO0 pins are for address/command input and data output to and from the 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 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. 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. READ ENABLE: RE# Please refer to Section 8-1 for details. 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#. WRITE ENABLE: WE# When the WE# goes low, the address/data/ command are latched at the rising edge of WE#. 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#.

SCHEMATIC CELL LAYOUT AND ADDRESS ASSIGNMENT MX30LFxGE8AB NAND device is divided into two planes for 2Gb and 4Gb (the 1Gb is single plane), which is composed by 64 pages of (2,048+64)-byte in two NAND strings structure with 32 serial connected cells in each string. Each page has an additional 64 bytes for bad block marks and other purposes. The device has an on-chip buffer of 2,112 bytes for data load and access. Each 2K-Byte page has the two area, one is the main area which is 2048-bytes and the other is spare area which is 64-byte. There are four (for 1Gb) or five (for 2Gb/4Gb) address cycles for the address allocation, please refer to the table below. Table 1.

Page Read The MX30LFxGE8AB array is accessed in Page of 2,112 bytes. 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 MX30LFxGE8AB 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. Figure 6.

Page Program The memory is programmed by page, which is 2,112 bytes. 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 (A[17:12]). 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. Figure 11.

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.

Status Read The MX30LFxGE8AB 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 4-1 and Table 4-2. Table 4-1.

Status Enhance Read The 2Gb and 4Gb support the two-plane operation, the Status Enhanced Read command (78h) offers the alternative method besides the Status Read command to get the status of specific plane in the same NAND Flash device. The result information is outlined in Table 4-1 and Table 4-2. The [SR]6 and SR[5] bits are shared with all planes. However, the SR[0], SR[1], SR[3], SR[4] are for the status of specific plane in the row address. The Status Enhanced Read command is not allowed at power-on Reset (FFh) command and OTP enabled.

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. The internal ECC is disabled on the parameter page. Figure 21.

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 6-11. 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. The internal ECC is disabled on the unique ID. 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. P/N: PM1975 REV. 1.1, MAY 04, 2015 40 MX30LF1GE8AB MX30LF2GE8AB MX30LF4GE8AB Figure 23.

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 08h 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. 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 4 per each OTP page. Figure 27.

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. Figure 31.

The internal ECC is always enabled. After the data transfer time (tR_ECC) is completed, a Status Read command (70h) is required to check any uncorrectable read error happened. Please refer to Table 4-1. Status Output and Table 4-2. ECC Bit Status. The constraint of the internal ECC operation: • The ECC protection coverage: please refer to Table 7-1 & 7-2. The Distribution of ECC Segment and Spare Area. Only the grey areas are under internal ECC protection when the internal ECC is enabled. • The number of partial-page program is not 4 in an ECC segment, the user need to program the main area (512B) + spare area (1st 8-byte for 4Gb and whole 16-byte for 1Gb/2Gb) together at one time of program operation, so the ECC parity code can be calculated properly and stored in the additional hidden spare area.

Two-Plane Operations The 2Gb/4Gb NAND device is divided into two planes for performance improvement. In the two-plane operation, the NAND device may proceed the same type operation (for example- Program, or Erase) on the two planes concurrent or overlapped by the two-plane command sets. The different type operations cannot be done in the two-plane operations; for example, it cannot be done to erase one plane and program the other plane concurrently. The plane address A18 must be different from each selected plane address. The page address A12-A17 of individual plane must be the same for two-plane operation. The Status Read command( 70h) may check the device status in the two-plane operation, if the result is failed and then the Status Enhanced Read (78h) may check which plane is failed. 6-14. Two-plane Program (ONFI) and Two-plane Cache Program (ONFI) The two-plane program command (80h-11h) may input data to cache buffer and wait for the final plane data input with command (80h-10h) and then transfer all data to NAND array. As for the two-plane cache program operation, it can be achieved by a two-plane program command (80h-11h) with a cache program command (80h-15h), and the final address input with the confirm command (80h-10h). Please refer to the waveforms of two-plane program and two-plane cache program for details. The random data input command (85h) can be also used in the two-plane program operation for changing the column address, please refer to the waveform of two-plane program with random data input. Notes: 1. Page number should be the same for both planes. 2. Block address [29:18] can be different. For examples: If the user issues 80h-(block address 5h, page address 5h) -11h - 80h - (block address - 18h, page address 5h) - 10h, the programmed page is - Plane 0: block address 18h, page address 5h - Plane 1: block address 5h, page address 5h (Note: Block address = A [29:18], page address = A [17:12]) P/N: PM1975 REV. 1.1, MAY 04, 2015 52 MX30LF1GE8AB MX30LF2GE8AB MX30LF4GE8AB Figure 32-1.

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.

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 38. 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 bytes of the 1st and 2nd page in the spare area for bad block will be 00h. 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. Table 16.

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. Figure 39. Bad Block Test Flow Start Block No. = 0 Yes (Note 1) Read 00h Check Create (or Update) Bad Block Table No Block No. = Block No. + 1 (Note 2) Block No. = 1023 No Yes End Note 1. Read 00h check is at the 1st byte of the 1st and 2nd pages of the block spare area. 2. The Block No. = 1023 for 1Gb, 2047 for 2Gb, 4095 for 4Gb.
