(200ns). the device may reset if trp < trp min(200ns), but this is not guaranteed. warm reset will abort the current nand flash core operation. duri ng a warm reset, the content of memory cells being altered is no longer valid as the data will be partially programmed or erased. warm reset has no effect on contents of bootram and dataram. 3.3.3 hot re set mode operation see timing diagram 6.13 a hot reset means that the host resets the device by reset command. the reset command can be either command based or register based. upon receiving the reset command, the device lo gic stops all current operation and executes an internal reset operation and resets the current nand flash core operation. during an internal reset operation, the device initializes inte rnal registers and makes output signals go to default status. th e bufferram data is kept unchanged after warm/hot reset operations. hot reset will abort the current nand flash core operation. duri ng a hot reset, the content of memory cells being altered is no longer valid as the data will be partially programmed or erased. hot reset has no effect on contents of bootram and dataram. 3.3.4 nand flash co re reset mode operation see timing diagram 6.14 the host can reset the nand flash core operation by issuing a na nd flash core reset command. nand flash core reset will abort the current nand flash core operation. during a nand flash core reset, the content of memory cells being altered is no lo nger valid as the data will be partially programmed or erased. nand flash core reset has an effect on neither cont ents of bootram and dataram nor register values. at system power-up, the voltage detector in the device detects the rising edge of vcc and releases an internal power-up reset s ignal. this triggers bootcode loading. bootcode loading means that t he boot loader in the device copi es designated sized data (1kb) fr om the beginning of memory into the bootram. this sequence is the cold reset of onenand. the por(power on reset) triggering le vel is typically 1.5v. boot code copy operation activates 400us after por. therefore, the system power should reach 1.7v within 400us from the por triggering level for bootcode data to be valid. it takes approximately 70us to copy 1kb of bootcode. upon completi on of loading into the bootram, it is available to be read by the host. the int pin is not available until afte r iobe = 1 and iobe bit can be changed by host. 3.3.1 cold reset mode operation see timing diagram 6.11

(locked-tight state can be achieved via lock-tight command which follows lock command) only one block can be released from lock state to unlock state with unlock command and addresses. the unlocked block can be changed with new lock command. therefore, each bl ock has its own lock/unlock/lock-tight state. unlock command sequence: start block address+unlock block command (0023h) unlocked 3.4.3.2 locked nand array writ e protection state a locked block cannot be programmed or eras ed. all blocks default to a locked state fo llowing a cold or warm reset. unlocked blocks can be changed to locked using the lock block command. the status of a lo cked block can be changed to unlocked or locked-tight using the appropriate software command. lock command sequence: start block address+lock block command (002ah) locked 3.4.3.1 unlocked nand array write protection state

onenand1g(kfg1g16q2m-deb6) flash memory 122 onenand2g(kfh2g16q2m-deb6) onenand4g(kfw4g16q2m-deb6) one of the best features onenand has is t hat it can be a booting device itself since it contains an internally built-in boot lo ader despite the fact that its core architecture is based on nand flash. 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 th en 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 i s larger than 1kb and less than or equal to 3kb, only 1kb of it can be mo ved to bootram automatically and fetched by cpu, and the rest o f it can be loaded into one of the datarams w hose size is 2kb by load command and cpu can take it from the dataram after finish- ing the code-fetching job for bootram. if it s size is larger than 3kb, the 1kb portion of it can be moved to bootram automatica lly 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 patition of nand flash array and onenand boot sequence. in this boot scheme, boot code is comprised of b l1, where bl stands for boot loader, bl2, and bl3. moreover, the size of the boot code is larger than 3kb (the 3rd case above). b l1 is called primary boot loader in other words. here is the ta ble of detailed explanations about the function of eac h boot loader in this specific boot scheme. boot loaders in onenand nand flash array of onenand is divided into the partitions as de scribed at partition of nand flash array to show where each component of code is located and how much portion of the over all nand flash array each one occupies. in addition, the boot sequence is listed below and depicted at boot sequence. boot loader description bl1 moves bl2 from nand flash array to dra m through two datarams using dual buffering bl2 moves os image (or bl3 opt ionally) from nand flash array to dram through two datarams using dual buffering bl3 (optional) moves or writes the image through usb interface 7.2.1 boot loaders in onenand boot sequence : 1. power is on bl1 is loaded into bootram 2. bl1 is executed in bootram bl2 is loaded into dram through two datarams using dual buffering by bl1 3. bl2 is executed in dram os image is loaded into dram through two datarams using dual buffering by bl2 4. os is running 7.2.2 boot sequence 7.2 boot sequence
