GENERAL DESCRIPTION OneNAND is a single-die chip with standard NOR Flash interface using NAND Flash Array. This device is comprised of logic and NAND Flash Array and 5KB internal BufferRAM. 1KB BootRAM is used for reserving bootcode, and 4KB DataRAM is used for buffering data. The operating clock frequency is up to 54MHz. This device is X16 interface with Host, and has the speed of ~76ns random access time. Actually, it is accessible with minimum 4clock latency(host-driven clock for synchronous read), but this device adopts the appropriate wait cycles by programmable read latency. OneNAND provides the multiple sector read operation by assigning the number of sectors to be read in the sector counter register. The device includes one block sized OTP(One Time Programmable), which can be used to increase system security or to provide identification capabilities. 7 OneNAND512/OneNAND1GDDP FLASH MEMORY 3. PIN DESCRIPTION Pin Name Type Nameand Description Host Interface A15~A0 I Address Inputs - Inputs for addresses during read operation, which are for addressing BufferRAM & Register. I/O Data Inputs/Outputs - Inputs data during program and commands during all operations, outputs data during memory array/ register read cycles. Data pins float to high-impedance when the chip is deselected or outputs are disabled. INT O Interrupt Notifying Host when a command has completed. It is open drain output with internal resistor(~50kohms). After power-up, it is at hi-z condition. Once IOBE is set to 1, it does not float to hi-z condition even when the chip is deselected or when outputs are disabled. RDY O Ready Indicates data valid in synchronous read modes and is activated while CE is low CLK I Clock CLK synchronizes the device to the system bus frequency in synchronous read mode. The first rising edge of CLK in conjunction with AVD low latches address input. WE I Write Enable WE controls writes to the bufferRAM and registers. Datas are latched on the WE pulse's rising edge AVD I Address Valid Detect Indicates valid address presence on address inputs. During asynchronous read operation, all addresses are latched on AVD's rising edge, and during synchronous read operation, all addresses are latched on CLK's rising edge while AVD is held low for one clock cycle. > Low : for asynchronous mode, indicates valid address ;for burst mode, causes starting address to be latched on rising edge on CLK > High : device ignores address inputs RP I Reset Pin When low, RP resets internal operation of OneNAND. RP status is don't care during power-up and bootloading. CE I Chip Enable CE-low activates internal control logic, and CE-high deselects the device, places it in standby state, and places A/DQ in Hi-Z OE I Output Enable OE-low enables the device's output data buffers during a read cycle.

Boot area data is only returned if no command has been issued prior to the read. 8.1 Command based operation The entire address range, except for the boot area, can be used for the data buffer. All commands are written to the boot partition. Writes outside the boot partition are treated as normal writes to the buffers or registers. The command consists of one or more cycles depending on the command. After completion of the command the device starts its execution. Writing incorrect information which include address and data or writing an improper command will terminate the previous command sequence and make the device go to the ready status.

Reset will return all default values into the device. 8.1.4 Load Data into Buffer Load Data into Buffer command is a two-cycle command. Two sequential designated command activates this operation. Sequentially writing 00E0h and 0000h to the boot partition [0000h~01FFh, 8000h~800Fh] will load one page to DataRAM0. This operation refers to FBA and FPA. FSA, BSA, and BSC are not considered. At the end of this operation, FPA will be automatically increased by 1. So continuous issue of this command will sequentially load data in next page to DataRAM0. This page address increment is restricted within a block. The default value of FBA and FPA is 0. Therefore, initial issue of this command after power on will load the first page of memory, which is usually boot code. 8.1.5 Read Identification Data Read Identification Data command consists of two cycles. It gives out the devices identification data according to the given address. The first cycle is 0090h to the boot partition address and second cycle is read from the addresses specified in Table5. 39 OneNAND512/OneNAND1GDDP FLASH MEMORY Table 4.

And the designated size data(1KB) is copied from the beginning of the memory to the BootRAM. After the bootcode loading is completed, the BootRAM is always locked to protect the significant boot code from the accidental write. Write Protection for NAND Flash array Write Protection Modes The device offers both hardware and software write protection features for NAND Flash array. The software write protection feature is used by writing Lock command or Lock-tight command to command register;The 002Ah or 002Ch command is written into F220h register. And the hardware write protection feature is used by executing cold or warm reset. The default state is locked, and all NAND Flash array goes to locked state after cold or warm reset. Write Protection Commands The instant secured block protects code and data by allowing blocks to be locked or lock-tighten. The write protection scheme offers two levels of protection. The first allows software-only control of write protection(useful for frequently changed data blocks), while the second requires hardware interaction before locking can be changed(protects infrequently changed code blocks). The followings summarize the locking functionality > All blocks power-up in a locked state. Unlock commands can unlock these blocks. >The lock-tight command makes locked block(s) lock-tighten block(s). And lock-tight state can be returned to lock state only when cold or warm reset is asserted. > Lock-tighten blocks offer the user an additional level of write protection beyond that of a regular locked block. Lock-tighten block can't have it's state changed by software, it can be changed by warm reset or cold reset. > Unlock start and end block address are reflected immediately to the device only when the unlock command is issued, and NAND Flash write protection status register is also updated at that time. > Unlocked blocks can be programmed or erased. > Only one consecutive area can be released to unlock state from lock state, i.e unlocking multi area is not available. > Partial block lock (a range) is not available, i.e lock operation is only available for all blocks. Write Protection Status The device current Write Protection status can be read in NAND Flash Write Protection Status Register(F24Eh). There are three bits - US, LS, LTS -, which are not cleared by hot reset. These Write Protection status registers are updated when Write Protection command is entered. The followings summarize locking status. example1) In default, [2:0] values are 010. -> If host executes unlock block operation, then [2:0] values turn to 110. -> If host executes lock-tight block operation, then [2:0] values turn to 101. example2) If host executes lock block operation, then [2:0] values turn to 010. -> If host executes lock-tight block operation, then [2:0] values turn to 001. -> If cold or warm reset is entered, then [2:0] values turn to 010. 46 OneNAND512/OneNAND1GDDP FLASH MEMORY RP pin: High & Start block address End block address +Unlock block Command (Note 1) Lock RP pin: High & Lock block Command unlock Lock or RP pin: High & Start block address End block address +Unlock block Command Cold reset or Warm reset Power On Lock RP pin: High & Lock-tight block Command Cold reset or Warm reset Lock unlock RP pin: High & Lock-tight block Command Lock-tight Lock Lock-tight unlock Lock-tight NOTE: 1.

Figure 10. Operations of NAND Flash Write Protection 48 OneNAND512/OneNAND1GDDP FLASH MEMORY Load Operation The load operation is initiated by setting up the start address from which the data is to be loaded. The load command is issued in order to initiate the load. The device transfers the data from NAND Flash array into the BufferRAM. The ECC is checked and any detected and corrected error is reported in the status response as well as any unrecoverable error. When the BufferRAM has been filled an interrupt is issued to the host in order to read the contents of the BufferRAM. The read from the BufferRAM consist of asynchronous read mode or synchronous read mode. The status information related to the BufferRAM fill operation can be checked by the host if required. The device provides dual data buffer memory architecture. The device is capable of data-read operation from one data buffer and data-load operation to the other data buffer simultaneously. Refer to the information for more details in "Read while Load operation".

Load operation flow-chart 49 OneNAND512/OneNAND1GDDP FLASH MEMORY Read Operation The device has two read configurations ; Asynchronous read and Synchronous burst read. The initial state machine makes the device to be automatically entered into asynchronous read mode to prevent the memory content from spurious altering upon device power up or after a hardware reset. No commands are required to retrieve data in asynchronous mode. The synchronous mode will be enabled by setting RM bit of System configuration1 register to Synchronous read mode. Asynchronous Read Mode (RM = 0) For the asynchronous read mode a valid address should be asserted on ADD0-ADD15, while driving AVD and CE to VIL. WE should remain at VIH . The data will appear on ADD15-ADD0. Address access time (tAA) is equal to the delay from valid addresses to valid output data. The chip enable access time(tCE) is the delay from the falling edge of CE to valid data at the outputs. The output enable access time(tOE) is the delay from the falling edge of OE to valid data at the output. Synchronous (Burst) Read Mode (RM = 1) The device is capable of continuous linear burst operation and linear burst operation of a preset length. For the burst mode, the host should determine how many clock cycles are desired for the initial word(tIAA) of each burst access using BRL bit of System configuration 1 register. The registers also can be read during burst read mode by using AVD signal with a address. To initiate the synchronous read again, a new address during CE low toggle is needed after the host has completed status reads or the device has completed the program or erase operation. Continuous Linear Burst Read The initial word is output tIAA after the rising edge of the first CLK cycle. Subsequent words are output tBA after the rising edge of each successive clock cycle, which automatically increments the internal address counter. The RDY output indicates this condition to the system by pulsing low. The device will continue to output sequential burst data, wrapping around after it reaches the designated location(See Figure 12 for address map information) until the system asserts CE high, RP low or AVD low in conjunction with a new address. The cold/warm/hot reset or asserting CE high or WE low pulse terminate the burst read operation. If the device is accessed synchronously while it is set to asynchronous read mode, it is possible to read out the first data without problems.

Wrap around Programmable Burst Read Latency The programmable burst read latency feature indicates to the device the number of additional clock cycles that must elapse after AVD is driven active before data will be available. Upon power up, the number of total initial access cycles defaults to four clocks. The number of total initial access cycles is programmable from four to seven cycles. Rising edge of the clock cycle following last read latency triggers next burst data CE CLK 0 1 2 3 4 5 -1 6 AVD tBA Valid Address A0: A15 D6 D7 D0 D1 D2 D3 DQ0: DQ15 D7 D0 tIAA Hi-Z RDY tRDYS OE tRDYA Hi-Z Figure 13. Example of 4clock Burst Read Latency Handshaking The handshaking feature allows the host system to simply monitor the RDY signal from the device to determine when the initial word of burst data is ready to be read. To set the number of initial cycle for optimal burst mode, the host should use the programmable burst read latency configuration.(See "System Configuration1 Register" for details.) The rising edge of RDY which is derived from 1 clock ahead of data fetch clock indicates the initial word of valid burst data. Output Disable Mode When the CE or OE input is at VIH , output from the device is disabled. The outputs are placed in the high impedance state. 51 OneNAND512/OneNAND1GDDP FLASH MEMORY Program Operation The device can be programmed in data unit. Programming is writing 0's into the memory array by executing the internal program routine. In order to perform the Internal Program Routine, command sequence is necessary. First, host sets the address of the BufferRAM and the memory location and loads the data to be programmed into the BufferRAM. Second, program command initiates the internal program routine. During the execution of the Routine, the host is not required to provide further controls or timings. During the Internal Program Routine, commands except reset command written to the device will be ignored. Note that a reset during a program operation will cause data corruption at the corresponding location. The device provides dual data buffer memory architecture. The device is capable of data-write operation from host to one of data buffers during program operation from anther data buffer to Flash simultaneously.

Since the time-consuming cycles of serial access and re-loading 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 serial access and copying-program with the address of destination page.

Data from the source page is saved in one of the on-chip DataRAM buffers and modified by the host, then programmed into the destination page. As shown in the flow chart, data modification is possible upon completion of load operation. ECC is also available at the end of load operation. Therefore, using hardware ECC of OneNAND, accumulation of 1 bit error can be avoided.

To erase a block is to write 1s into the desired memory block by executing the Internal Erase Routine. In order to perform the Internal Erase Routine, command sequence is necessary. First, host sets the block address of the memory location. Second, erase command initiates the internal erase routine. During the execution of the Routine, the host is not required to provide further controls or timings.

But this OTP block could not be erased. This block is separated from NAND Flash Array, so it could be accessed by OTP Access command instead of FBA. If user wants to exit from OTP access mode, Cold, Warm and Hot Reset operation should be done. OTP area is one block size(128KB, 64pages) and is divided by two areas. The first area from page 0 to page 9, total 10pages, is assigned for user and the second area from page 10 to page 63, total 54pages, are occupied for the device manufacturer. The manufacturer area is programmed prior to shipping, so this area could not be used by user. This block is fully guaranteed to be a valid block.

INT OE WE 0~15 DQ 0~15 ADD Page A Write While Program OneNAND512/OneNAND1GDDP FLASH MEMORY OneNAND512/OneNAND1GDDP FLASH MEMORY ECC Operation While the device transfers data from BufferRAM to NAND Flash Array Page Buffer for Program Operation, the device hiddenly generates ECC(24bits for main area data and 10bits for 2nd and 3rd word data of each sector spare area) and while Load operation, hiddenly generates ECC and detects error number and position and corrects 1bit error. ECC is updated by the device automatically. After Load Operation, host can know whether there is error or not by reading 'ECC Status Register'(refer to ECC Status Register Table). In addition, OneNAND supports 2bit EDC even though it is little probable that 2bit error occurs. Hence, it is not recommeded that Host reads 'ECC Status Register' for checking ECC error because the built-in Error Correction Logic of OneNAND finds out and corrects ECC error. When the device loads NAND Flash Array main and sprea area data with ECC operation, the device does not place the newly generated ECC for main and spare area into the buffer but places ECC which was generated and written in program operation into the buffer. Ecc operation is done during the boot loading operation. ECC Bypass Operation ECC bypass operation is set by 9th bit of System Configuration 1 register. In ECC Bypass operation, the device neither generates ECC result which indicates error position nor updates ECC code to NAND Flash arrary spare area in program operation(refer to ECC Result Register Tables). During Load operation, the on-chip ECC engine does not generate a new ECC internally and the values of ECC Status and Result Registers are invalid. Hence, in ECC Bypass operation, the error cannot be detected and corrected by MuxOneNAND itself. ECC Bypass operation is not recommended to host. Table 7.

Data Protection during Power Down 63 OneNAND512/OneNAND1GDDP FLASH MEMORY Technical Notes Invalid Block(s) Invalid blocks are defined as blocks that contain one or more invalid bits whose reliability is not guaranteed by Samsung. The information regarding the invalid block(s) is so called as the invalid block information. Devices with invalid block(s) have the same quality level as devices with all valid blocks and have the same AC and DC characteristics. An invalid block(s) does not affect the performance of valid block(s) because it is isolated from the bit line and the common source line by a select transistor. The system design must be able to mask out the invalid block(s) via address mapping. The 1st block, which is placed on 00h block address, is fully guaranteed to be a valid block. Identifying Invalid Block(s) All device locations are erased(FFFFh) except locations where the invalid block(s) information is written prior to shipping. The invalid block(s) status is defined by the 1st word in the spare area. Samsung makes sure that either the 1st or 2nd page of every invalid block has non-FFFFh data at the 1st word of sector0 spare area. Since the invalid block information is also erasable in most cases, it is impossible to recover the information once it has been erased. Therefore, the system must be able to recognize the invalid block(s) based on the original invalid block information and create the invalid block table via the following suggested flow chart. Any intentional erasure of the original invalid block information is prohibited. Start Set Block Address = 0 Increment Block Address Create (or update) Invalid Block(s) Table No * Check " FFFFh" ? Check "FFFFh" at the 1st word of sector0 spare area at the 1st and 2nd page in the block Yes No Last Block ? Yes End Figure 22. Flow chart to create invalid block table. 64 OneNAND512/OneNAND1GDDP FLASH MEMORY Technical Notes (Continued) Error in write or load operation Within its life time, additional invalid blocks may develop with the device. Refer to the qualification report for the actual data.The following possible failure modes should be considered to implement a highly reliable system. In the case of status read failure after erase or program, block replacement should be done. Because program status fail during a page program does not affect the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased empty block and reprogramming the current target data and copying the rest of the replaced block.

Thus, OneNAND does not make any additional booting device necessary for a system, which imposes extra cost or area overhead on the overall system. As the system power is turned on, the boot code originally stored in NAND Flash Arrary is moved to BootRAM automatically and then fetched by CPU through the same interface as SRAM's or NOR Flash's if the size of the boot code is less than 1KB. If its size is larger than 1KB and less than or equal to 3KB, only 1KB of it can be moved to BootRAM automatically and fetched by CPU, and the rest of it can be loaded into one of the DataRAMs whose size is 2KB by Load Command and CPU can take it from the DataRAM after finishing the code-fetching job for BootRAM. If its size is larger than 3KB, the 1KB portion of it can be moved to BootRAM automatically and fetched by CPU, and its remaining part can be moved to DRAM through two DataRAMs using dual buffering and taken by CPU to reduce CPU fetch time. A typical boot scheme usually used to boot the system with OneNAND is explained at Figure 24 and Figure 25. In this boot scheme, boot code is comprised of BL1, where BL stands for Boot Loader, BL2, and BL3. Moreover, the size of the boot code is larger than 3KB (the 3rd case above). BL1 is called primary boot loader in other words. Here is the table of detailed explanations about the function of each boot loader in this specific boot scheme. Boot Loaders in OneNAND Boot Loader Description BL1 Moves BL2 from NAND Flash Array to DRAM through two DataRAMs using dual buffering BL2 Moves OS image (or BL3 optionally) from NAND Flash Array to DRAM through two DataRams using dual buffering BL3 (Optional) Moves or writes the image through USB interface NAND Flash Array of OneNAND is divided into the partitions as described at Figure 24 to show where each component of code is located and how much portion of the overall NAND Flash Array each one occupies. In addition, the boot sequence is listed below and depicted at Figure 25. Boot Sequence : 1. Power is on BL1 is loaded into BootRAM 2.

OneNAND Boot Sequence 69 OneNAND512/OneNAND1GDDP FLASH MEMORY Technical Notes (Continued) Methods of Determining Interrupt Status There are two methods of determining Interrupt Status on the OneNAND. Using the INT pin or monitoring the Interrupt Status Register Bit. The OneNAND INT pin is an output pin function used to notify the Host when a command has been completed. This provides a hardware method of signaling the completion of a program, erase, or load operation. In its normal state, the INT pin is high if the INT polarity bit is default. Before a command is written to the command register, the INT bit must be written to '0' so the INT pin transitions to a low state indicating start of the operation. Upon completion of the command operation by the OneNAND's internal controller, INT returns to a high state. INT is an open drain output allowing multiple INT outputs to be Or-tied together. INT does not float to a hi-Z condition when the chip is deselected or when outputs are disabled. Refer to section 2.8 for additional information about INT. INT can be implemented by tying INT to a host GPIO or by continuous polling of the Interrupt status register. The INT Pin to a Host General Purpose I/O INT can be tied to a Host GPIO to detect the rising edge of INT, signaling the end of a command operation. COMMAND INT This can be configured to operate either synchronously or asynchronously as shown in the diagrams below. 70 OneNAND512/OneNAND1GDDP FLASH MEMORY Technical Notes (Continued) Synchronous Mode Using the INT Pin When operating synchronously, INT is tied directly to a Host GPIO. Host OneNAND CE CE AVD AVD CLK CLK RDY RDY OE OE GPIO INT Asynchronous Mode Using the INT Pin When configured to operate in an asynchronous mode, /CE and /AVD of the OneNAND are tied to /CE of the Host.

Host OneNAND CE CE AVD Vss CLK N.C RDY OE OE GPIO INT Polling the Interrupt Register Status Bit An alternate method of determining the end of an operation is to continuously monitor the Interrupt Status Register Bit instead of using the INT pin.
