Preliminary HY27US(08/16)1G1M Series 1Gbit (128Mx8bit / 64Mx16bit) NAND Flash 1. SUMMARY DESCRIPTION
The HYNIX HY27US(08/16)1G1M series is a 128Mx8bit with spare 4Mx8 bit capacity. The device is offered in 3.3V Vcc Power Supply. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. The device contains 8192 blocks, composed by 32 pages consisting in two NAND structures of 16 series connected Flash cells. A program operation allows to write the 512-byte page in typical 200us and an erase operation can be performed in typical 2ms on a 16Kbyte(X8 device) block. Data in the page mode can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command input. This interface allows a reduced pin count and easy migration towards different densities, without any rearrangement of footprint. Commands, Data and Addresses are synchronously introduced using CE, WE, ALE and CLE input pin. The on-chip Program/Erase Controller automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. The modifying can be locked using the WP input pin. The output pin R/B (open drain buffer) signals the status of the device during each operation. In a system with multiple memories the R/B pins can be connected all together to provide a global status signal. Even the write-intensive systems can take advantage of the HY27US(08/16)1G1M extended reliability of 100K program/erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm. Optionally the chip could be offered with the CE don't care function. This option allows the direct download of the code from the NAND Flash memory device by a microcontroller, since the CE transitions do not stop the read operation. The copy back function allows the optimization of defective blocks management: when a page program operation fails the data can be directly programmed in another page inside the same array section without the time consuming serial data insertion phase. The HYNIX HY27US(08/16)1G1M series is available in 48 - TSOP1 12x20 mm, 48 - USOP1 12 x 17 mm.

1.2 PIN DESCRIPTION
Pin Name IO0-IO7 IO8-IO15(1) Description DATA INPUTS/OUTPUTS The IO pins allow to input command, address and data and to output data during read / program operations. The inputs are latched on the rising edge of Write Enable (WE). The I/O buffer float to High-Z when the device is deselected or the outputs are disabled. COMMAND LATCH ENABLE This input activates the latching of the IO inputs inside the Command Register on the Rising edge of Write Enable (WE). ADDRESS LATCH ENABLE This input activates the latching of the IO inputs inside the Address Register on the Rising edge of Write Enable (WE). CHIP ENABLE This input controls the selection of the device. When the device is busy CE low does not deselect the memory. WRITE ENABLE This input acts as clock to latch Command, Address and Data. The IO inputs are latched on the rise edge of WE. READ ENABLE The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the falling edge of RE which also increments the internal column address counter by one. WRITE PROTECT The WP pin, when Low, provides an Hardware protection against undesired modify (program / erase) operations. READY BUSY The Ready/Busy output is an Open Drain pin that signals the state of the memory. SUPPLY VOLTAGE The VCC supplies the power for all the operations (Read, Write, Erase). GROUND NO CONNECTION

Preliminary HY27US(08/16)1G1M Series 1Gbit (128Mx8bit / 64Mx16bit) NAND Flash 2. BUS OPERATION
There are six standard bus operations that control the device. These are Command Input, Address Input, Data Input, Data Output, Write Protect, and Standby. Typically glitches less than 5 ns on Chip Enable, Write Enable and Read Enable are ignored by the memory and do not affect bus operations.
2.1 Command Input.
Command Input bus operation is used to give a command to the memory device. Command are accepted with Chip Enable low, Command Latch Enable High, Address Latch Enable low and Read Enable High and latched on the rising edge of Write Enable. Moreover for commands that starts a modifying operation (write/erase) the Write Protect pin must be high. See figure 5 and table 12 for details of the timings requirements. Command codes are always applied on IO7:0, disregarding the bus configuration (X8/X16).
2.2 Address Input.
Address Input bus operation allows the insertion of the memory address. Four cycles are required to input the addresses for the 1Gbit devices. Addresses are accepted with Chip Enable low, Address Latch Enable High, Command Latch Enable low and Read Enable high and latched on the rising edge of Write Enable. Moreover for commands that starts a modify operation (write/erase) the Write Protect pin must be high. See figure 6 and table 12 for details of the timings requirements. Addresses are always applied on IO7:0, disregarding the bus configuration (X8/X16). In addition, addresses over the addressable space are disregarded even if the user sets them during command insertion.
2.3 Data Input.
Data Input bus operation allows to feed to the device the data to be programmed. The data insertion is serially and timed by the Write Enable cycles. Data are accepted only with Chip Enable low, Address Latch Enable low, Command Latch Enable low, Read Enable High, and Write Protect High and latched on the rising edge of Write Enable. See figure 7 and table 12 for details of the timings requirements.
2.4 Data Output.
Data Output bus operation allows to read data from the memory array and to check the status register content, the lock status and the ID data. Data can be serially shifted out toggling the Read Enable pin with Chip Enable low, Write Enable High, Address Latch Enable low, and Command Latch Enable low. See figures 13 to 17 and table 12 for details of the timings requirements.
2.5 Write Protect.
Hardware Write Protection is activated when the Write Protect pin is low. In this condition modify operation do not start and the content of the memory is not altered. Write Protect pin is not latched by Write Enable to ensure the protection even during the power up.
2.6 Standby.
In Standby mode the device is deselected, outputs are disabled and Power Consumption is reduced.

3.1 Page Read.
Upon initial device power up, the device defaults to Read1 mode. This operation is also initiated by writing 00h to the command register along with followed by the four address input cycles. Once the command is latched, it does not need to be written for the following page read operation. Three types of operations are available: random read, serial page read and sequential row read. The random read mode is enabled when the page address is changed. The 528 bytes (x8 device) or 264 word (x16 device) of data within the selected page are transferred to the data registers in less than access random read time tR (15us). The system controller can detect the completion of this data transfer tR (15us) by analyzing the output of R/B pin. Once the data in a page is loaded into the registers, they may be read out in 50ns cycle time by sequentially pulsing RE. High to low transitions of the RE clock output the data stating from the selected column address up to the last column address. After the data of last column address is clocked out, the next page is automatically selected for sequential row read. Waiting tR again allows reading the selected page. The sequential row read operation is terminated by bringing CE high. The way the Read1 and Read2 commands work is like a pointer set to either the main area or the spare area. Writing the Read2 command user may selectively access the spare area of bytes 512 to 527. Addresses A0 to A3 set the starting address of the spare area while addresses A4 to A7 are ignored. Unless the operation is aborted, the page address is automatically incremented for sequential row Read as in Read1 operation and spare sixteen bytes of each page may be sequentially read. The Read1 command (00h/01h) is needed to move the pointer back to the main area. Figure_10 to 12 show typical sequence and timings for each read operation. Devices with automatic read of page0 at power up can be provided on request.
3.2 Page Program.
The device is programmed basically on a page basis, but it does allow multiple partial page programming of a byte or consecutive bytes up to 528 (x8 device), in a single page program cycle. The number of consecutive partial page programming operation within the same page without an intervening erase operation must not exceed 8; for example, 4 times for main array (X8 device:1time/512byte, X16 device:1time 256word) and 4 times for spare array (X8 device:1time/16byte ,X16 device:1time/8word). The addressing may be done in any random order in a block. A page program cycle consists of a serial data loading period in which up to 528 bytes (x8 device) or 264 word (x16 device) of data may be loaded into the page register, followed by a non-volatile programming period where the loaded data is programmed into the appropriate cell. Serial data loading can be started from 2nd half array by moving pointer. About the pointer operation, please refer to Figure_22. The data-loading sequence begins by inputting the Serial Data Input command (80h), followed by the four address input cycles and then serial data loading. The Page Program confirm command (10h) starts the programming process. Writing 10h alone without previously entering the serial data will not initiate the programming process. The internal Program Erase Controller automatically executes the algorithms and timings necessary for program and verify, thereby freeing the system controller for other tasks. Once the program process starts, the Read Status Register command may be entered, with RE and CE low, to read the status register. The system controller can detect the completion of a program cycle by monitoring the R/B output, or the Status bit (I/O 6) of the Status Register. Only the Read Status command and Reset command are valid while programming is in progress. When the Page Program is complete, the Write Status Bit (I/O 0) may be checked Figure_14 The internal write verify detects only errors for "1"s that are not successfully programmed to "0"s. The command register remains in Read Status command mode until another valid command is written to the command register.

3.3 Block Erase.
The Erase operation is done on a block (16K Byte) basis. It consists of an Erase Setup command (60h), a Block address loading and an Erase Confirm Command (D0h). The Erase Confirm command (D0h) following the block address loading initiates the internal erasing process. This two-step sequence of setup followed by execution command ensures that memory contents are not accidentally erased due to external noise conditions. The block address loading is accomplished in four cycles depending on the device density. Only block addresses (A14 to A26) are needed while A9 to A13 is ignored. At the rising edge of WE after the erase confirm command input, the internal Program Erase Controller handles erase and erase-verify. When the erase operation is completed, the Write Status Bit (I/O 0) may be checked. Figure_16 details the sequence.
3.4 Copy-Back Program.
The copy-back program is provided to quickly and efficiently rewrite data stored in one page within the plane to another page within the same plane without using an external memory. Since the time-consuming sequential-reading and its reloading cycles are removed, the system performance is improved. The benefit is especially obvious when a portion of a block is updated and the rest of the block also need to be copied to the newly assigned free block. The operation for performing a copy-back program is a sequential execution of page-read without burst-reading cycle and copying-program with the address of destination page. A normal read operation with "00h" command and the address of the source page moves the whole 528byte data into the internal buffer. As soon as the device returns to Ready state, Page-Copy Data-input command (8Ah) with the address cycles of destination page followed may be written. The Program Confirm command (10h) is required to actually begin the programming operation. Copy-Back Program operation is allowed only within the same memory plane. Once the Copy-Back Program is finished, any additional partial page programming into the copied pages is prohibited before erase. Plane address must be the same between source and target page "When there is a program-failure at Copy-Back operation, error is reported by pass/fail status. But, if Copy-Back operations are accumulated over time, bit error due to charge loss is not checked by external error detection/correction scheme. For this reason, two bit error correction is recommended for the use of Copy-Back operation." Figure 15 shows the command sequence for the copy-back operation. The Copy Back Program operation requires three steps: - 1. The source page must be read using the Read A command (one bus write cycle to setup the command and then 3 bus cycles to input the source page address.) This operation copies all 264 Words/ 528 Bytes from the page into the page Buffer. - 2. When the device returns to the ready state (Ready/Busy High), the second bus write cycle of the command is given with the 4cycles to input the target page address. A26, A25 must be the same for the Source and Target Pages. - 3. Then the confirm command is issued to start the P/E/R Controller. Note: 1. Copy-Back Program operation is allowed only within the same memory plane. 2. On the same plane, It's prohibited to operate copy-back program from an odd address page (source page) to an even address page (target page) or from an even address page (source page) to an odd address page (target page). Therefore, the copy-back program is permitted just between odd address pages or even address pages.

3.5 Read Status Register.
The device contains a Status Register which may be read to find out whether read, program or erase operation is completed, and whether the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE does not need to be toggled for updated status. Refer to table 13 for specific Status Register definitions. The command register remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read cycle, a read command (00h or 50h) should be given before sequential page read cycle.
3.6 Read ID.
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of 00h. Two read cycles sequentially output the manufacturer code (ADh), the device code and 3rd, 4 cycle ID respectively. The command register remains in Read ID mode until further commands are issued to it. Figure 17 shows the operation sequence, while tables 15 explain the byte meaning.
3.7 Reset.
The device offers a reset feature, executed by writing FFh to the command register. When the device is in Busy state during random read, program or erase mode, the reset operation will abort these operations. The contents of memory cells being altered are no longer valid, as the data will be partially programmed or erased. The command register is cleared to wait for the next command, and the Status Register is cleared to value E0h when WP is high. Refer to table 14 for device status after reset operation. If the device is already in reset state a new reset command will not be accepted by the command register. The R/B pin transitions to low for tRST after the Reset command is written. Refer to figure 19.

4.1 Data Protection & Power on/off Sequence
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector disables all functions whenever Vcc is below about 2.0V(3.3V device). WP pin provides hardware protection and is recommended to be kept at VIL during power-up and power-down. A recovery time of minimum 10us is required before internal circuit gets ready for any command sequences as shown in Figure 20. The two-step command sequence for program/erase provides additional software protection. If the power is dropped during the ready read/write/erase operation, Power protection function may not guaranteed the data. Power protection function is only available during the power on/off sequence.
4.2 Ready/Busy.
The device has a Ready/Busy output that provides method of indicating the completion of a page program, erase, copy-back, cache program and random read completion. The R/B pin is normally high and goes to low when the device is busy (after a reset, read, program, erase operation). It returns to high when the internal controller has finished the operation. The pin is an open-drain driver thereby allowing two or more R/B outputs to be Or-tied. Because pull-up resistor value is related to tr(R/B) and current drain during busy (Ibusy), an appropriate value can be obtained with the following reference chart (Fig 21). Its value can be determined by the following guidance.
4.3 Power-On Auto-Read
The device is designed to offer automatic reading of the first page without command and address input sequence during power-on. An internal voltage detector enables auto-page read functions when Vcc reaches about 1.8V. Serial access may be done after power-on without latency. Power-On Auto Read mode is available only on 3.3V device.

System Interface Using CE don't care
To simplify system interface, CE may be deasserted during data loading or sequential data-reading as shown below. So, it is possible to connect NAND Flash to a microprocessor. The only function that was removed from standard NAND Flash to make CE don't care read operation was disabling of the automatic sequential read function.

Bad Block Management
Devices with Bad Blocks have the same quality level and the same AC and DC characteristics as devices where all the blocks are valid. A Bad Block does not affect the performance of valid blocks because it is isolated from the bit line and common source line by a select transistor. The devices are supplied with all the locations inside valid blocks erased(FFh/FFFFh). The Bad Block Information is written prior to shipping. Any block where the 6th Byte/ 1st Word in the spare area of the 1st or 2nd page (if the 1st page is Bad) does not contain FFh/FFFFh is a Bad Block. The Bad Block Information must be read before any erase is attempted as the Bad Block Information may be erased. For the system to be able to recognize the Bad Blocks based on the original information it is recommended to create a Bad Block table following the flowchart shown in Figure 26. The 1st block, which is placed on 00h block address is guaranteed to be a valid block.
Block Replacement
Over the lifetime of the device additional Bad Blocks may develop. In this case the block has to be replaced by copying the data to a valid block. These additional Bad Blocks can be identified as attempts to program or erase them will give errors in the Status Register. As the failure of a page program operation does not affect the data in other pages in the same block, the block can be replaced by re-programming the current data and copying the rest of the replaced block to an available valid block. The Copy Back Program command can be used to copy the data to a valid block.
See the "Copy Back Program" section for more details.
Refer to Table 16 for the recommended procedure to follow if an error occurs during an operation. Operation Erase Program Read Recommended Procedure Block Replacement Block Replacement or ECC (with 4bit/528byte) ECC (with 4bit/528byte)
