SUMMARY DESCRIPTION The HYNIX HY27(U/S)S(08/16)561A series is a 32Mx8bit with spare 8Mx16 bit capacity. The device is offered in 1.8V Vcc Power Supply and 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 2048 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 16K-byte(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 HY27(U/S)S(08/16)561A extended reliability of 100K program/erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm. The chip could be offered with the CE don't care function. This function 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. This device includes also extra features like OTP/Unique ID area, Block Lock mechanism, Automatic Read at Power Up, Read ID2 extension. The Hynix HY27(U/S)S(08/16)561A series is available in 48 - TSOP1 12 x 20 mm , 48 - USOP1 12 x 17 mm, FBGA 9 x 11 mm. 1.1 Product List PART NUMBER ORIZATION HY27SS08561A x8 HY27SS16561A x16 HY27US08561A x8 HY27US16561A x16 Rev 0.5 / Jun. 2006 VCC RANGE PACKAGE 1.70 - 1.95 Volt 63FBGA / 48TSOP1 / 48USOP1 2.7V - 3.6 Volt 4 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 9&& &( ,2a,2 ,2a,2 [2QO\ :( 5% 5( $/( &/( :3 35( 966 Figure1: Logic Diagram IO15 - IO8 Data Input / Outputs (x16 Only) IO7 - IO0 Data Input / Outputs CLE Command latch enable ALE Address latch enable CE Chip Enable RE Read Enable WE Write Enable WP Write Protect R/B Ready / Busy Vcc Power Supply Vss Ground NC No Connection PRE Power-On Read Enable, Lock Unlock Table 1: Signal Names Rev 0.5 / Jun. 2006 5 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 1& 1& 1& 1& 1& 1& 5% 5( &( 1& 1& 9FF 9VV 1& 1& &/( $/( :( :3 1& 1& 1& 1& 1& 1$1')ODVK 7623 [ 1& 1& 1& 1& ,2 ,2 ,2 ,2 1& 1& 35( 9FF 9VV 1& 1& 1& ,2 ,2 ,2 ,2 1& 1& 1& 1& 1& 1& 1& 1& 1& 1& 5% 5( &( 1& 1& 9FF 9VV 1& 1& &/( $/( :( :3 1& 1& 1& 1& 1& 1$1')ODVK 7623 [ 9VV ,2 ,2 ,2 ,2 ,2 ,2 ,2 ,2 1& 35( 9FF 1& 1& 1& ,2 ,2 ,2 ,2 ,2 ,2 ,2 ,2 9VV Figure 2. 48TSOP1 Contactions, x8 and x16 Device 1& 1& 1& 1& 1& 1& 5% 5( &( 1& 1& 9FF 9VV 1& 1& &/( $/( :( :3 1& 1& 1& 1& 1& 1$1')ODVK 8623 [ 1& 1& 1& 1& ,2 ,2 ,2 ,2 1& 1& 35( 9FF 9VV 1& 1& 1& ,2 ,2 ,2 ,2 1& 1& 1& 1& 1& 1& 1& 1& 1& 1& 5% 5( &( 1& 1& 9FF 9VV 1& 1& &/( $/( :( :3 1& 1& 1& 1& 1& 1$1')ODVK 8623 [ 9VV ,2 ,2 ,2 ,2 ,2 ,2 ,2 ,2 1& 35( 9FF 1& 1& 1& ,2 ,2 ,2 ,2 ,2 ,2 ,2 ,2 9VV Figure 3. 48USOP1 Contactions, x8 and x16 Device Rev 0.5 / Jun. 2006 6 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash $ 1& % 1& 1& & :3 ' $/( 9VV &( :( 5% 1& 5( &/( 1& 1& 1& ( 1& 1& 1& 1& 1& 1& ) 1& 1& 1& 1& 1& 1& * 1& 1& 1& 1& 1& 35( + 1& ,2 1& 1& 1& 9FF - 1& ,2 1& 9FF ,2 ,2 . 9VV ,2 ,2 ,2 ,2 9VV 1& 1& 1& 1& / 1& 1& 1& 1& 0 1& 1& 1& 1& Figure 4. 63FBGA Contactions, x8 Device (Top view through package) $ 1& % 1& 1& & :3 $/( 9VV &( :( 5% ' 1& 5( &/( 1& 1& 1& ( 1& 1& 1& 1& 1& 1& ) 1& 1& 1& 1& 1& 1& * 1& 1& 1& ,2 ,2 35( + ,2 ,2 ,2 ,2 ,2 9FF - ,2 ,2 ,2 9FF ,2 ,2 . 9VV ,2 ,2 ,2 ,2 9VV 1& 1& 1& 1& / 1& 1& 1& 1& 0 1& 1& 1& 1& Figure 5. 63FBGA Contactions, x16 Device (Top view through package) Rev 0.5 / Jun. 2006 7 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 1.2 PIN DESCRIPTION Pin Name IO0-IO7 IO8-IO15(1) CLE ALE CE WE RE WP R/B VCC VSS NC PRE Description DATA INPUTS/OUTPUTS The IO pins allow to input command, address and data and to output data during read / program operations.

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 7 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. Three bus cycles are required to input the addresses for the 256Mbit 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 8 and table 12 for details of the timings requirements. Addresses are always applied on IO7:0, disregarding the bus configuration (X8/X16). 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 9 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 10 to 14 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. Rev 0.5 / Jun. 2006 11 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 3. DEVICE OPERATION 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 three 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 (12us). The system controller can detect the completion of this data transfer tR (12us) 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_12 to 15 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 operations within the same page without an intervening erase operation must not exceed 2 for main array and 3 for spare array. 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_29, 30. The data-loading sequence begins by inputting the Serial Data Input command (80h), followed by the three 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_16. 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. Rev 0.5 / Jun. 2006 12 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 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 two to three cycles depending on the device density. Only block addresses (A14 to A24) 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_18 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 not needed to actually begin the programming operation. For backward-compatibility, issuing Program Confirm command during copy-back does not affect correct device 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 17 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 3cycles to input the target page address. A24 must be the same for the Source and Target Pages. - 3. Then the confirm command is issued to start the P/E/R Controller. Rev 0.5 / Jun. 2006 13 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 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. The command register remains in Read ID mode until further commands are issued to it. Figure 19 shows the operation sequence, while tables 13, 14 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 12 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 25. Rev 0.5 / Jun. 2006 14 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 4. OTHER FEATURES 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 1.1V(1.8V device), 2V(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 26. 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 27). Its value can be determined by the following guidance. 4.3 Lock Block Feature In high state of PRE pin, Block lock mode and Power on Auto read are enabled, otherwise it is regarded as NAND Flash without PRE pin. Block Lock mode is enabled while PRE pin state is high, which is to offer protection features for NAND Flash data. The Block Lock mode is divided into Unlock, Lock, Lock-tight operation. Consecutive blocks protects data allows those blocks to be locked or lock-tighten with no latency. This block lock scheme offers two levels of protection. The first allows software control (command input method) of block locking that is useful for frequently changed data blocks, while the second requires hardware control (WP low pulse input method) before locking can be changed that is useful for protecting infrequently changed code blocks. The followings summarized the locking functionality. - All blocks are in a locked state on power-up. Unlock sequence can unlock the locked blocks. - The Lock-tight command locks blocks and prevents from being unlocked. Lock-tight state can be returned to lock state only by Hardware control(WP low pulse input). 1. Block lock operation 1) Lock - Command Sequence: Lock block Command (2Ah). See Fig. 20. - All blocks default to locked by power-up and Hardware control (WP low pulse input) - Partial block lock is not available; Lock block operation is based on all block unit - Unlocked blocks can be locked by using the Lock block command, and a lock block's status can be changed to unlock or lock-tight using the appropriate commands - On the program or erase operation in Locked or Lock-tighten block, Busy state holds 1~10us(tLBSY) Rev 0.5 / Jun. 2006 15 HY27US(08/16)561A Series HY27SS(08/16)561A Series 256Mbit (32Mx8bit / 16Mx16bit) NAND Flash 2) Unlock - Command Sequence: Unlock block Command (23h) + Start block address + Command (24h) + End block address. See Fig. 21. - Unlocked blocks can be programmed or erased. - An unlocked block's status can be changed to the locked or lock-tighten state using the appropriate sequence of commands. - Only one consecutive area can be released to unlock state from lock state; Unlocking multi area is not available. - Start block address must be nearer to the logical LSB (Least Significant Bit) than End block address. - One block is selected for unlocking block when Start block address is same as End block address. 3) Lock-tight - Command Sequence: Lock-tight block Command (2Ch). See Fig. 22. - Lock-tighten blocks offer the user an additional level of write protection beyond that of a regular lock block. A block that is lock-tighten can't have its state changed by software control, only by hardware control (WP low pulse input); Unlocking multi area is not available - Only locked blocks can be lock-tighten by lock-tight command. - On the program or erase operation in Locked or Lock-tighten block, Busy state holds 1~10us(tLBSY) 4) Lock Block Boundaries after Unlock Command issuing - If Start Block address = 0000h and End Block Address = FFFFh , the device is all unlocked - If Start Block address = End Block Address = FFFFh , the device is all locked except for the last Block - If Start Block address = End Block Address = 0000h , the device is all locked except for the first Block 2. Block lock Status Read Block Lock Status can be read on a block basis to find out whether designated block is available to be programmed or erased. After writing 7Ah command to the command register and block address to be checked, a read cycle outputs the content of the Block Lock Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. RE or CE does not need to be toggled for updated status. Block Lock Status Read is prohibited while the device is busy state. Refer to table 16 for specific Status Register definitions. The command register remains in Block Lock Status Read mode until further commands are issued to it. In high state of PRE pin, write protection status can be checked by Block Lock Status Read (7Ah) while in low state by Status Read (70h). 4.4 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. PRE pin controls activation of auto-page read function. Auto-page read function is enabled only when PRE pin is logic high state. Serial access may be done after power-on without latency. Power-On Auto Read mode is available only on 3.3V device.

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).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 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 33. 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 17 for the recommended procedure to follow if an error occurs during an operation.
