Block Replacement
* Step1
When an error happens in the nth page of the Block ’ A’ during erase or program operation.
* Step2
Copy the nth page data of the Block ’ A’ in the buffer memory to the nth page of another free block. (Block ’ B’ )
* Step3
Then, copy the data in the 1st ~ (n-1)th page to the same location of the Block ’ B’ .
* Step4
Do not further erase Block ’ A’ by creating an ’ invalid Block’ table or other appropriate scheme.
