: If program operation results in an error, map out
the block including the page in error and copy the
target data to another block.

Error in write or read operation
Over its life time, the additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the actual
data.The following possible failure modes should be considered to implement a highly reliable system. In the case of status read fail-
ure after erase or program, block replacement should be done. To improve the efficiency of memory space, it is recommended that
the read or verification failure due to single bit error be reclaimed by ECC without any block replacement. The said additional block
failure rate does not include those reclaimed blocks.
Failure Mode
Detection and Countermeasure sequence
Write
Erase Failure
Status Read after Erase --> Block Replacement
Program Failure
Status Read after Program --> Block Replacement
Read back ( Verify after Program) --> Block Replacement
or ECC Correction
Read
Single Bit Failure
Verify ECC -> ECC Correction
ECC
: Error Correcting Code --> Hamming Code etc.
Example) 1bit correction & 2bit detection
