Referring to the diagram for further illustration, when an error happens in the nth page of block 'A' during program operation, copy the data in
the 1st ~ (n-1)th page to the same location of block 'B' via data buffer0.
Then copy the nth page data of block 'A' in the data buffer1 to the nth page of block 'B' or any free block. Do not further erase or program block
'A' but instead complete the operation by creating an 'Invalid Block Table' or other appropriate scheme.
