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 DataRAM.
Then re-program the nth page 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.
