Abstract
Method and apparatus for sanitizing a memory using bit-inverted data. In accordance with various embodiments, a memory location is sanitized by sequential steps of reading a bit value stored in a selected memory cell of the memory, inverting the bit value, and writing the inverted bit value back to the selected memory cell. The memory cell may be erased between the reading and writing steps, as well as after the writing step. Random bit values may be generated and stored to the memory cell, and run-length limited constraints can be used to force bit-inversions.
