mbm30lv0128 10 n n n n functional description read mode there are three distinct commands used for the read operation : 00h, 01h, and 50h. after the command cycle, three address cycles are used to input the starting address. upon the rising edge of the final we pulse, there is a 10 m s latency in which the 528 byte page is transferred to the data register. the r/b signal may be used to monitor the completion of the data transfer. once the data page has been loaded into the data register, it may be clocked out with consecutive 50 ns re pulses. each re pulse will automatically advance the column address by one. once the last column has been read, the page address will automatically increment by one and the data register will be updated with the new page after 10 m s. in this sequential read operation, the ce signal must stay low after the third address input and during busy state. if the ce signal goes high during this period, the read operation will be terminated and then the standby mode will be entered. (in the read operation, after read command and address input, the ce signal can be dont care after the third address input and during busy state.) the 00h read command will set the pointer to the first half of the page of the array while the 01h read command sets it in the second half. it may be logical to think of 00h as a command which sets a 8 = 0 while 01h sets a 8 = 1. the 50h command sets the pointer to the spare area, consisting of columns 512 to 527. during this read mode, a 3 to a 0 is used to set the starting address of the spare area. as with the 00h and 01h operations, once the spare area page is loaded into the data register, it may be read out by re pulses. each re pulse will increment the column address until the final column (527) is reached. at this time, the pointer will be reset to column 512 while the page address is incriminated and the data register is updated. (in this sequential read operation also, ce signal must stay low after the third address input and during busy state.) the 00h or 01h command is required to move the pointer back into the main array area. read (1) , (2) : 00h/01h the read (1) , (2) mode is invoked by latching the 00h or 01h command into the command register. this mode (00h) will automatically be selected when the device powers up. cle ce we ale re i/o0 to i/o7 y x x r/b 00h data output starting address command 01h 0 255 511 527 (column address) page (row) address x yy figure 2 read mode (1) , (2) operation
mbm30lv0128 11 read (3) : 50h the read (3) mode has identical timing to that of read (1) and (2) . however, while read (1) and (2) are used to access the array, read (3) is used to access the 16 byte spare area. when the 50h command is executed, the pointer will be set to an address space between columns 512 and 527. the values of y will complete the address decoding. during this operation, only address bits a 3 to a 0 are used to determine the starting column address; a 7 to a 4 are ignored. a 23 to a 9 are used to determine the starting row address. sequential read each re pulse used to output data from the data register will cause the column address pointer to increment by one. when the final column has been reached, the next page will be automatically loaded into the data register. the r/b signal may be used to monitor the completion of the data transfer. cle ce we ale re i/o0 to i/o7 y x x r/b 50h data output starting address command 0 255 511 527 (column address) page (row) address x y figure 3 read mode (3) operation 0 i/o0 to i/o7 r/b address input data data data 00h/01h/50h 0 255 511 527 50h, se = l 0 255 511 527 00h, se = h 0 255 511 527 01h, se = l 0 255 511 527 00h, se = l figure 4 sequential read
mbm30lv0128 12 page program : 80h, 10h the device is programmed either by the page or partial page. programming is done by issuing the 80h command followed by three address cycles then serial data input. the 80h command may be preceded by either 00h, 01h or 50h to set the pointer to either the first half page, second half page, or spare area respectively. if the pointer command is not specifically issued, its location is determined by its previous use (see application note (2) ) . after the serial data input, any column address which did not receive new data will not be programmed. this enables a page to be partially programmed. after the data has been entered, the 10h command will initiate the embedded programming process. if the 10h command is issued without loading any new data, programming will not be initiated. a given page may not be partially programmed more than five consecutive times without an intervening erase operation. during the programming cycle, the r/b pin or status register bit i/o6 may be used to monitor the completion of the programming cycle. only the reset and read status commands are valid while programming is in progress. after programming, the status register bit i/o0 should be checked to verify whether the procedure was successful or not. double page progam : 82h, 10h the device has a double page program function to program two consecutive pages of data in 2 flash pages. the page must firstly be in the order of even page data (528 bytes) followed by odd page data secondly (528 bytes) .the 82h command may be preceded by 00h, 01h or 50h to set the pointer to the first half of even page, or to the second half of even page or to the spare area of even page respectively. if the pointer command is not specifically issued, its location is determined by its previous use. other use or operations are the same as page program operations which use 80h command. (partial program, to input 10h command, r/b , status register.) block erase : 60h, d0h the device data is erased in a block consisting of sixteen pages. the erase operation begins with the 60h command followed by two address cycles in which the block to be erased is entered. while the two address cycles require a 23 to a 9 to be entered, a 13 to a 9 are dont care bits. once the block address is successfully loaded, the d0h command is entered to initiate the erase operation. the r/b signal may be used to monitor the completion of the cycle. upon completion, the status register bit i/o0 should be used to verify a successful erase. 10h 70h i/o0 address and data input 80h i/o0 to i/o7 r/b 0 = pass 1 = fail figure 5 page program d0h 70h i/o0 address input 60h i/o0 to i/o7 r/b 0 = pass 1 = fail figure 6 block erase
mbm30lv0128 13 read id : 90h this mode allows the identification of the manufacturer and product. after the 90h command cycle, one address cycle follows in which 00h is entered. the next two re pulses will output the manufacturer and device codes respectively. table 5 code table status read : 70h the status register may be used to determine if the device is ready, in the write protect mode, or passed program/erase operations. after the 70h command is entered, the more recent falling edge of either ce or re will output the contents of the status register to i/o0 to 7. the status register is continually updated and does not require either ce or re to be toggled. by utilizing the ce pin, multiple devices with r/b pins wired together may be polled to determine their specific status. table 6 status output table i/o7 i/o6 i/o5 i/o4 i/o3 i/o2 i/o1 i/o0 code manufacturer 00000100 04h device 01110011 73h status description i/o0 program/erase 0 = pass; 1 = fail i/o1 not used i/o2 not used i/o3 not used i/o4 not used i/o5 not used i/o6 ready/busy 0 = busy; 1 = ready i/o7 write protect 0 = protected; 1 = unprotected 73h 04h 90h 00h re i/o0 to i/o7 manufacturer code device code figure 7 read id operation
mbm30lv0128 14 reset when the device is busy during program, erase, or read, it can be reset by entering the command ffh. if wp equals 1, the status register will be set to c0h. if a reset command is issued while the device is in the reset state, the command will be ignored. if the device is reset during the program or erase operations, the internal high voltages will be discharged before r/b goes high. device (1) ce (1) device (2) ce (2) device (n) ce (n) 0/1 0/1 ale cle we re 8 i/o0 to i/o7 r/b r/b ale cle we ce (1) ce (n) re i/o0 to i/o7 status of device (1) status of device (n) 70h 70h figure 8 status read ffh r/b i/o0 to i/o7

(2) pointer action for program operation the pointer action can be done for program operation as follows. start only 50h area program? start address is in 00h area? input 01h command input 00h command *2 program sequence continue to program? the pointer is 01h? start address area (00h,01h,50h) is the same as the previous? program sequence start address area is changed from 01h to 00h? set 01h command input read command *3 continue to program? end input 50h command *1 yes no yes no no yes yes no no yes yes no yes no *1 : if the read operation was done by setting the start address in 50h within the area in previous use, the 50h command input can be skipped. *2 : if the read operation was done at 00h or (and) 01h area during previous use, the 00h command input can be skipped. *3 : the read command means 00h, 01h or 50h. 0 255 511 527 00h 01h 50h figure 24 pointer action flow chart
mbm30lv0128 30 (3) acceptable commands after serial input command 80h when the serial input command (80h) is input for program execution, commands other than the program execution command (10h) or reset command (ffh) should not be input. if a command other than 10h or ffh is input, the program operation is not performed. (4) status read during the read operation when the status read command (70h) is input during reading, the next re clock signal can be input to read the value of the internal status register. since the internal operation mode is held in status read, read data will not be output even if the re clock signal is input after becoming ready. status read is therefore disabled at reading. when the read command (00h) is input during the period [a], the internal operation mode of the device can be canceled, making it possible to read data at address n without inputting add. (5) auto program failure 80 ff address input we r/b figure 25 reset command after 80h input 10 xx 80 other command programming will not be executed. in case of this operation, the ffh command is needed. 00 70 00 [a] n address status read command input status output status read we r/b ce re figure 26 status read during read operation if programming at page address (m) fails, data should be programmed at the page address (n) of another block. data input at first programming at page address (m) will be lost. so address input using the 80h command must follow the same procedure as data input. 80 10 70 80 80 10 i/o 10 fail address m data input address n data input n m figure 27 auto program failure
mbm30lv0128 31 (6) r/b : termination of the ready/busy pin (r/b ) the r/b is open-drain output. when using the r/b , r/b must be pulled up v cc by a resistor. (7) power on/off sequence : after power-off, each input signal level may be undefined. use the wp signal as shown in the figure below. device v cc v cc r c l r/b v ss v cc max. - v ol i ol + i l 3.2 v 8 ma + i l r = = figure 28 termination for r/b 2.7 v 2.5 v v cc 0 v ce, we, re cle, ale wp don't care v il v ih operation don't care v il figure 29 power on/off sequence
mbm30lv0128 32 (8) setup for wp signal a low-level wp signal will force erasing and programming to be reset. to control, use the wp signal as shown below. we din wp r/b 80 10 t ww program 100 ns (min.) we din wp r/b 80 10 t ww program prohibition 100 ns (min.) we din wp r/b 60 d0 t ww erase 100 ns (min.) we din wp r/b 60 d0 t ww erase prohibition 100 ns (min.)
mbm30lv0128 33 (9) address input in 4 cycles the device will get addresses in three cycles. if addresses are input in four cycles, address input in the fourth cycle will be ignored by the chip. internal read operation starts when we in the third cycle goes high. read operation ignored cle ce we ale i/o0 to i/o7 r/b 00h , 01h or 50h address input figure 30 read operation when 4 address cycles are input program operation cle ce we ale i/o0 to i/o7 80h address input ignored data input figure 31 program operation when 4 address cycles are input
mbm30lv0128 34 (10) divided programming on same page the device uses a page programming method that allows programming for up to five times on the same page. the procedure for divided programming (programming on a part of one page) is shown below. (11) notification for re signal when the device is in the read mode, the re signal causes the internal column address counter to increment in synchronization with the re clock. if the 00h, 01h, or 50h command is input to the device in the read mode, the internal column address counter will count up even after the re signal is input prior to address input. at this mode, and at input of the re signal beyond the last column address, the device will start reading (memory ? register) even without address input and may output the busy signal (sequential read is started) . in this way, once the device enters the read mode, unintentional reading may be started after the re signal is input prior to addressing; therefore, the re signal should be input after the address input. data pattern 1 column a column b page n the first programming data pattern 2 column c column d page n the second programming data pattern 3 column e column f page n the third programming "no input" or "1" data pattern 1 column a column b page n result data pattern 2 column c column d data pattern 3 column e column f "no input" or "1" "no input" or "1" "no input" or "1" "no input" or "1" "1" "1" "1" figure 32 divided program in the same page 00h/01h /50h i/o0 to i/o7 we address input re r/b figure 33 re input before address
mbm30lv0128 35 (12) invalid block (bad block) the device contains unusable blocks. therefore, the following issues must be recognized : (13) failure phenomena for program and erase operations repeated rewriting might cause an error at programming and erasing. possible error modes, detection methods and remedies are listed in the following table. system-based remedies will provide a highly reliable system. * : (1) or (2) ? ecc : error correcting code ? hamming code etc. example : 1 bit correction & 2 bit detection. ? block replacement erase if an error occurs at erasing, like programming, remedies should be executed on a system basis to prevent access to blocks causing the error. failure mode detection and countermeasure sequence block erase failure status read after erase ? block replacement page program failure status read after prog. ? block replacement single bit* program failure 1 ? 0 (1) block verify after prog. ? retry (2) ecc bad block bad block valid (good) block number min. 1014 max. 1024 unit block figure 36. shows the bad block test flow some mbm30lv0128 products have invalid blocks (bad blocks) at shipping. after mounting the device in the system, test whether there are no bad blocks. if there are any bad blocks, they should not be accessed. the bad blocks are connected to sense-amp of the bit lines via the selector transistors. good blocks will not be affected unless the bad blocks are accessed. the effective number of good blocks specified by fujitsu is shown below. figure 34 bad block program buffer memory error occurs block a block b if an error occurs in block a, reprogramming from the external buffer to block b is recommended. block a should not be accessed after an error occurs. figure 35 reprogramming to good block
