Abstract
A non-volatile memory system is configured to permanently erase a single file from a block of non-volatile memory cells. That block is storing programmed data including the single file to be erased and other programmed data. The single file is erased from the block such that the other programmed data in the block is not moved or otherwise disturbed.
