Error in write or read operation
Within 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
failure after erase or program, block replacement should be done. Because program status fail during a page program does not
affect the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an
erased empty block and reprogramming the current target data and copying the rest of the replaced block. In case of Read, ECC
must be employed. 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.
