The device may fail during a Program or Erase operation.
ECC: Error Correction Code
Block Replacement
Program
Erase
When an error occurs in an Erase operation, prevent future accesses to this bad block
(again by creating a table within the system or by using another appropriate scheme).

reprogram the data into another Block (Block B)
by loading from an external buffer. Then,
prevent further system accesses to Block A (by
creating a bad block table or by using an
another appropriate scheme).
