ABSTRACT:
Provided are a method and device for logging changes to blocks in a non-volatile memory. Security bits are maintained for blocks of cells in a non-volatile memory device indicating whether data in the blocks has been modified. The security bit for one block is set to indicate modification in response to detecting that at least one cell in the block was modified.
