Cell-level realization of burn after reading for NAND flash
Abstract:
The present disclosure generally relates to a method of burning a file in a memory device after the file has been read. Once a file has been read, an algorithm uses the memory device to create errors that the error correction code (ECC) cannot decode the error. In creating the error, the entire word line is destroyed physically rather than logically so that retrieving information from that particular word line is no longer possible. In creating the error, adjacent word lines are not affected. The error renders the file burned.
