When program operation is abnormally aborted (ex. power-down, reset), not only page data under program but also a
coupled row paired page data may be damaged. For example, during Page Program operation of page address 05h is
aborted by reset or power down, the data of 00h, 01h, 04h, and 05h page address may be spoiled.
7.2. Extra Block Description
Device includes extra features like user OTP, Unique ID and Read ID2. User OTP, Unique ID can be programmed only
once and cannot be erased. The user OTP used one block which locates the second block of plane 0 (address<31:22>
= 0002h). Unique ID block has 64 pages, locates the first block of plane 0 and the first 64 pages of the block
(address<32:22> = 0000h, address<21:14> = 00h ~ 3Fh). Read ID2 can be only read, the size is one page. Physi-
cally, ReadID2 area exists in plane1, but user block address does not care internally. To exit extra features, 07h or FFh
command can be used.
7.3. Acceptable Command after 80h
After Program Start Command (80h) is inputted, do not input any command except 85h, 10h, 11h, 15h, and FFh. If a
command is inputted except these commands, the program operation cannot be executed.
7.4. Acceptable Command between Start command and Confirm command
Only Reset Command is available between start commands and confirm commands set (start command-address-con-
firm command style) that is mentioned in 1.7 Command Set. If other command is inputted, the operation cannot be
executed. Do not input any commands except FFh. For instance, it is impossible to perform a normal Page Read oper-
ation, if any command is inputted between Page Read Command Set (00h - 5 address cycle - 30h).
7.5. Restriction of Read Status Value in Multi Plane Operation
During Multi plane operation, only 70h, 78h, and FFh are available between 11h-81h. But, the pass/fail output informa-
tion of 70h and 78h is not valid. During this time, only ready / busy (I/O6 and I/O5) state can be checked. Refer to Fig-
ure 63.
