muxonenand512(kfm1216q2m) flash memory 4 2. general description muxonenand is a single-die chip with muxed nor flash interface using na nd 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 buff- ering data. the operating clock frequency is up to 54mhz(1.8v devic e). this device is x16 interface with host, and has the spee d of ~76ns random access time. actually, it is accessible with minimum 4clo ck latency(host-driven clock for synchronous read), but t his device adopts the appropriate wait cycles by programmable read lat ency. muxonenand provides the multiple sector read operation by assigning the number of sectors to be read in the sector count er register. the device include s one block sized otp(one time programmable), which can be used to increase system securi ty or to provide identification capabilities.

muxonenand512(kfm1216q2m) flash memory 45 8.5 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 bee n filled an interrupt is issued to the host in order to read the c ontents of the bufferram. the read from the bufferram consist o f asyn- chronous read mode or synchronous read mode. the status inform ation 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 oper ation". figure 11. load operation flow-chart start write 0 to interrupt register add: f241h dq=0000h write ?dfs*, fba? of flash add: f100h dq=dfs*?, fba write ?fpa, fsa? of flash add: f107h dq=fpa, fsa write ?bsa, bsc? of dataram add: f200h dq=bsa, bsc select dataram for ddp add: f101h dq=dbs write ?load? command add: f220h dq=0000h or 0013h wait for int register low to high transition add: f241h dq[15]=int read controller add: f240h dq[14]=fc dq[14]=0? no yes * dbs, dfs is for ddp status register host reads data from dataram read completed dq=00 or 01? no yes ecc status register add: ff00h dq[0:7]=erm,ers load lock fail load fail
muxonenand512(kfm1216q2m) flash memory 46 8.6 read operation the device has two read configurations ; as ynchronous read and synchronous burst read. the initial state machine makes the device to be automatically entered into asynchronous read mode to prevent the memory conten t from spurious altering upon device power up or after a hardware reset. no commands are required to retrieve data in asynchronou s mode. the synchronous mode will be enabled by setting rm bit of system configuration1 register to synchronous read mode. 8.6.1 asynchronous read mode (rm = 0) for the asynchronous read mode a valid address should be asserted on adq0-adq15, while driving avd and ce to v il . we should remain at v ih . the data will appear on adq15-adq0. 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. 8.6.2 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, t he 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 and avd toggle is needed after the host has co mpleted status reads or the device has completed the program or erase operation. 8.6.3 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 au tomatically increments the internal address coun ter. the rdy output indicates this condition to the system by pulsing low. the device will continue to output se quential burst data, wrapping around to designated address after it reaches the designated location(see figure 12) 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 synchronous ly while it is set to asynchronous read mode, it is possible to read out the first data wi thout 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 buffer0 bufs 0(32w) 8010h~802fh bufs 1(32w) 8030h~804fh buffer1 reserved spare 8050h~8fffh n/a reg. reserved reg. 9000h~efffh register(4kw) f000h~ffffh reg. not support not support not support figure 12. the boundary of synchronous read * reserved area is not available on synchronous read
