Data encryption to provide data security and memory cell bit wear leveling

摘要

Method and apparatus for encrypting and storing data to provide data security and memory cell bit wear leveling. In accordance with various embodiments, input data are provided for writing to a target page of memory in a storage array. A seed value is derived from a count value indicative of a number of times a write access has occurred on the target page of memory. A block encryption routine is applied to the input data using the seed value to generate encrypted output data that are thereafter written to the target page.
