Abstract
A memory system performs analog sanitization of memory using a partial programming operation to overwrite existing data taking into account the relative voltage levels in the memory cells. By taking into account the relative voltage levels, the timing of a partial programming operation can be controlled to provide matched voltage levels in the memory cells so that conventional computer forensic techniques for data recovery are ineffective.
