For Errors in program or erase operations
The device may fail during a program or erase operation. Failure mode can be confirmed by read out the
status register after complete the erase and program operations. There are two failure modes specified by
each codes:
1: Status register error flag: I/O6 = V
Replace sector under the “Spare Sectors Replacement Flow at Status Register I/O6 Read”. Replacement must
be applied to one sector(2k bytes) which contains failure bits.
2: Status register error flag: I/O6 = V
Escape the program data temporary under the “Replacement Flow at Status Register I/O6 Read”. If failure
data can be corrected by ECC, do not replace to spare sector. If failure data can not be corrected by ECC,
replace to spare sector. Replacement must be applied to one sector(2k bytes) which contains failure bits.
