comprised of logic and nand flash array and 5kb internal bufferram. 1kb bootram is used for reserving bootcode, and 4kb dataram is used for buff- ering data. the operating clock frequency is up to 54mhz. this device is x16 interface with host, and has the speed of ~76ns ran dom access time. actually, it is accessible with minimum 4clock latency(host-driven clock for synchronous read), but this device ado pts the appropriate wait cycles by programmable read latency. onenand provides the multiple sector read operation by assigning the num- ber 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. onenand512/onenand1gddp flash memory

which are for addressing bufferram & register. dq15~dq0 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 and does not float to hi-z condi- tion 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 controll 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. power supply v cc -core power for onenand core this is the power supply for onenand core. v cc -io power for onenand

command based and a register based interface for performing operations on the device, reading device id, writing data to buffer etc. the command based interface is active in the boot partition, i.e. commands can only be w ritten with a boot area address. boot area data is only returned if no command has been issued prior to the read. when reading and pro - gramming the device, the data handling is data unit based, i.e. one data is read at the time from nand flash array. the device h as inputs/outputs that accept both address and data information. 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 parti tion. writes outside the boot partition are treated as normal writes to the buffers or registers. the command consists of one or more cycles depending o n the command. after completion of the command the device starts its execution. writing incorrect information which include address and data or writi ng an improper com- mand will terminate the previous command sequence and make the device go to the ready status. device bus operations note : l=v il (low), h=v ih (high), x=don?t

flash core operation synchronized with the rising edge of rp . the device logic will not be reset in case rp pulses shorter than 200ns, but the device guarantees the logic reset operation in case rp pulse is longer than 200ns. nand flash core reset will abort current nand flash core operation. the contents of memory cells being altered are no longer valid as the data will be partially programmed

voltage detector in the device detects the rising edge of vcc and releases the internal power-up reset s ignal which triggers bootcode loading. 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 w rite. 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 featu re is used by writing lock command or lock-tight command to command 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 rese t. write protection commands the instant secured block protects code and data by allowing blocks to be locked or lock-tighten. the write protection scheme of fers 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 o nly 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 bi ts - us, ls, lts -, which are not cleared by hot reset. these write protection status registers are updated when write protection com- mand 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.

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 asyn- chronous 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 opera tion". copy-back program operation the copy-back program is configured to quickly and efficiently rewrite data stored in one page by sector unit(1/2/3/4 sector) wi thout utilizing an external memory. since the time-consuming cycles of serial access and re-loading cycles are removed, the system per for- mance 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. erase operation the device can be erased in block unit. to erase a block is to write 1 s 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 th e memory location. second, erase command initiates the internal erase routine. during the execution of the routine, the host is no t required to provide further controls or timings. during the internal erase routine, commands except reset command written to the device will be ignored. note that a reset during a erase operation will cause data corruption at the corresponding location. onenand512/onenand1gddp flash memory 46 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 v il . we should remain at v ih . the data will appear on add15-add0. address access time (t aa ) is equal to the delay from valid addresses to valid output data. the chip enable access time(t ce ) is the delay from the falling edge of ce to valid data at the outputs. the output enable access time(t oe ) 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, th e host should determine how many clock cycles are desired for the initial word(t iaa ) of each burst access using brl bit of system configura- tion 1 register. the registers also can be read during burst read mode by using avd signal with a address. to initiate the synchro- nous 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 t iaa after the rising edge of the first clk cycle. subsequent words are output t ba 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 to designated address after it reaches the designated location(see figure 11) 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. division add.map(word order) bootm(0.5kw) 0000h~01ffh buffer0 bufm 0(1kw) 0200h~05ffh bufm 1(1kw) 0600h~09ffh buffer1 reserved main 0a00h~7fffh n/a reg. boots(16w) 8000h~800fh

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 clock s. the number of total initial access cycles is programmable from four to seven cycles. table 4. burst address sequences start addr. burst address sequence(decimal)

device can be programmed in data unit. programming is writing 0's into the memory array by executing the internal program ro u- tine. in order to perform the internal program routine, command sequence is necessary. first, host sets the address of the buffe r- ram 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 buff- ers during program operation from anther data buffer to flash simultaneously. refer to the information for more details in "read while load operation". addressing for program operation within a block, the pages must be programmed consecutively from the lsb (least significant bit) page of the block to msb (most s ig- nificant bit) pages of

supports one block sized otp area, which can be read and programmed with the same sequence as normal operation. 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 devided by two areas. the first area from 1st page to 10th page, total 10pages , is assigned for user and the second area from 11th page to 64th page, total 54pages, are occupied for the device manufacturer. t he 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. page:2kb+64b sector(main area):512b

10bits for 2nd and 3rd word data of each sector spare area) and while read operation, h id- denly 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). error type is divided into ?no error?, ?1bit error(correctable) and ?2bit error(uncorrectable). when the device loads nand flash array main and sprea area data with ecc operation, the device doesn?t place the newly gener- ated 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. data protection during power down the device is designed to offer protection from any involuntary program/erase during power-transitions. an internal voltage dete ctor disables all functions whenever vcc is below about

more invalid bits whose reliability is not guaranteed by samsung. the i nfor- mation 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 perf or- mance of valid block(s) because it is isolated from the bit line and the common source line by a select transistor. the system d esign 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 guar- anteed to be a valid block. 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 invali d block has non-ffffh data at the 1st word of sector0 spare area. since the invalid block information is also erasable in most cas es, 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 cha rt. any intentional erasure of the original invalid block information is prohibited. * figure 15. flow chart to create invalid block table. start set block address = 0 check " increment block address last block ? end no yes yes create (or update) no invalid block(s) table

additional invalid blocks may develop with the device. refer to the qualification report for the actual da ta.the fol- lowing possible failure modes should be considered to implement a highly reliable system. in the case of status read failure aft er erase or program, block replacement should be done. because program status fail during a page program does not affect the data o f the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased empty block a nd reprogramming the current target data and copying the rest of the replaced block.
