(t r ). the system controller may detect the completion of this data transfer 90 ? (t r ) by analyzing the output of r/b# pin. once the data in a page is loaded into the data registers, they may be read out in 20 ? cycle time by sequentially pulsing re#. the repetitive high to low transitions of the re# clock make the device output the data starting from the selected column address up to the last column address. the device may output random data in a page instead of the consecutive sequential data by writing random data output command. the column address of next data, which is going to be out, may be changed to the address, which follows random data output command. random data output can be operated multiple times, regardless of how many times it is done in a page. random data output random data output operation changes the column address from which data is being read in the page register. random data output only is issued in ready state. refer to figure 33. http://www..net/ datasheet pdf - http://www..net/
preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 39 4.2. cache read (available only within a block) to improve page read throughput, cache read operation is used within a block. first step is same as normal page read, issuing a page read sequence (00 - 30h). after random access (r/b# returns to high), 31h command is latched into the command register. data is being transferred from the data register to the cache register. while cache register data is outputted, next page is transferred from memory cell to data register. r/b# will stay low during present page random accessing and previous page transferring to cache register. because it is not necessary to output a whole page data before issuing another 31h command, if serial data output time exceeds random access time (t r ), the random access time can be hidden. the subsequent pages are issued additional 31h commands. to terminate cache read, 3fh command should be issued. this command transfer data from data register to the cache register without issuing next page read. during the cache read operation, device doesn?t allow any other command except cache read command (31h), read status (70h, 78h, 75h), read (00h), and reset (ffh). to carry out other operations after cache operation, cache read must be ended by 3fh command or issue reset (ffh) before next operation. figure 34 : cache read 4.3. cache read enhanced (available only within a block) this command extends the cache read command. while, by issuing a cache read command, the next page address of the next page is automatically incremented by 1, the next page address of the next page is given arbitrarily by the user. the cache read enhanced command sequence consists of a 00h command, five address cycles and a 31h command, which replaces the single 31h command of the cache read command sequence. http://www..net/ datasheet pdf - http://www..net/
preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 40 figure 35 : multi plane page read 4.4. multi plane page read multi - plane page read is an extension of page read, for a single plane with 8,832byte page registers. since the device is equipped with two memory planes, activating the two sets of 8,832byte page resisters enables a random read of two pages. multi - plane page read is initiated by repeating command 60h followed by three address cycles twice. in this case, only same page of each block can be selected from each plane. after read confirm command (30h) the 17,664bytes of data within the selected two pages are transferred to the data registers in less than 90 ? (t r ). the system controller can detect the completion of data transfer (t r ) by monitoring the output of r/b# pin. once the data is loaded into the data registers, the data output of first plane can be read out by issuing command 00h with five address cycles, command 05h with two column address and finally e0h. the data output of second plane can be read out using the identical command sequences. the restrictions for multi - plane page read are shown in figure 35. multi - plane page read must be used in the block which has been programmed with multi - plane page program. http://www..net/ datasheet pdf - http://www..net/

preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 43 4.8. 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 read status (70h) or multi plane read status (78h,75h) command to the command register, a read cycle outputs the content of the status register to the i/o pins only if ce# and re# are low, 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. refer to 2.8. status register codings for specific status register definitions and figure 38, figure 39 for read status. the command register remains in read status mode until further commands are issued to it. therefore, if the status register is read during a random read cycle, the read command (00h) should be given before starting read cycles. figure 38 : read status figure 39 : multi plane read status http://www..net/ datasheet pdf - http://www..net/
preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 44 4.9. page program the device is programmed as a page unit. the number of consecutive partial page programming operation within the same page without an intervening erase operation must not exceed 1 times. the program addressing should be done in sequential order in a block. a page program cycle consists of a serial data loading period in which up to 8,832 bytes of data may be loaded into the data register, followed by a non - volatile programming period where the loaded data is programmed into the appropriate cell. the serial data - loading period begins by inputting the serial data input command (80h), followed by the five cycle address inputs and then serial data. the words other than those to be programmed do not need to be loaded. the device supports random data input in a page. the column address of next data, which will be entered, may be changed to the address which follows random data input command (85h). random data input may be operated multiple times, regardless of how many times it is done in a page. the page program confirm command (10h) initiates the programming process. writing 10h alone without previously entering the serial data will not initiate the programming process. the internal write state 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 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. the write status bit (i/o 0) is valid, when all internal operations are complete (status bit i/o 6 = high). 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. figure 40 and figure 41 details the sequence. figure 40 : page program figure 41 : random data input http://www..net/ datasheet pdf - http://www..net/
preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 45 4.10. multi plane program device supports multiple plane program. it is possible to program in parallel 2 pages, one per each plane. a multiple plane program cycle consists of a double serial data loading period in which up to 17,664bytes of data may be loaded into the data register, followed by a non - volatile programming period where the loaded data is programmed into the appropriate cell. the serial data loading period begins by inputting the serial data input command (80h), followed by the five cycle address inputs and then serial data for the 1st page. address for this page must be within first plane (a<22>=0). the data of first page other than those to be programmed do not need to be loaded. the device supports random data input exactly like page program operation. the dummy page program confirm command (11h) stops 1st page data input and the device becomes busy for a short time (t dbsy ). once it has become ready again, 81h command must be issued, followed by second page address (5 cycles) and its serial data input. address for this page must be within second plane (a<22>=1). the data of second page other than those to be programmed do not need to be loaded. program confirm command (10h) makes parallel programming of both pages start. user can check operation status by r/b# pin or read status register command, as if it were a normal page program; status register command is also available during dummy busy time (t dbsy ). in case of fail in first plane or second plane page program, fail bit of status register will be set: pass/fail status of each plane can be checked by multi plane read status. figure 42 details the sequence. figure 42 : multi plane page program notes: 1. plane 0 and plane 1 should be selected within the same chip 2. only one block should be selected from the each plane. 3. selected page address except a22 within two blocks must be same. 4. any command between 11h and 81h is prohibited except 70h/78h/75h and ffh. 5. read status command can be 70h or 78h or 75h. http://www..net/ datasheet pdf - http://www..net/
preliminary h27ubg8t2btr - bc series 32gb (4096m x 8bit ) legacy mlc nand flash rev 0.7 / jan. 2011 46 4.11. cache program (available only within a block) cache program is an extension of the standard page program, which is executed with 8,832 bytes cache registers and same bytes data register. after the serial data input command (80h) is loaded to the command register, followed by 5 cycles of address, a full or partial page of data is latched into the cache register, and then the cache write command (15h) is loaded to the command register. after that sequence, the data in the cache register is transferred into the data register for cell programming. at this time, the device remains in busy state. after all data of the cache register is transferred into the data register, the device goes to the ready state to load the next data into the cache register by issuing another cache program command sequence (80h - 15h). there are some restrictions for cache program operation. 1. the cache program command is available only within a block. 2. user must give address and data after 80h command. the busy time of first sequence equals the time it takes to transfer the data of cache register to the data register. cell programming of the data of data register and loading of the next data into the cache register is consequently processed as a pipeline method. on the second and cascading sequence, transfer from the cache register to the data register is held off until cell programming of current data register contents has been done. read status command (70h) may be issued to find out when the cache register is ready by polling the cache - busy status bit (i/o 6). in addition, the status bit (i/o 5) can be used to determine when the cell programming of the current data register contents is complete. pass/fail status of only the previous page (i/o 1) is available upon the return to ready state. if the system monitors the progress of programming only with r/b#, the last page of the target programming sequence must be programmed with actual page program command (10h). if the cache program command (15h) is used instead, status bit (i/o5) must be polled to find out when the last programming is actually finished before starting other operations such as read. pass/fail status is available in two steps. i/o 1 returns with the status of the previous page upon ready or i/o6 status bit changing to "1", and later i/o 0 with the status of current page upon true ready (returning from internal programming) or i/o 5 status bit changing to "1". i/o 1 may be read together when i/o 0 is checked. refer to 2.8. status register coding and figure 43 for more details. http://www..net/ datasheet pdf - http://www..net/
