Error in write or load operation
Within its life time, additional invalid blocks may develop with the device. Refer to the qualification report for the actual data.The fol-
lowing 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.

Block Replacement
When an error happens in the nth page of the Block ’A’ during program operation.
* Step1
Then, copy the data in the 1st ~ (n-1)th page to the same location of the Block ’B’ via data buffer0.
* Step2
Copy the nth page data of the Block ’A’ in the data buffer1 to the nth page of another free block. (Block ’B’)
Do not further erase or program Block ’A’ but create an ’invalid Block’ table or other appropriate scheme.
