Abstract
Provided are an apparatus, non-volatile memory storage device and method for detecting drift in in non-volatile memory. A determination is made as to whether bits to write have more of a first value than a second value. Each of the bits are flipped to another of the first or second value when the bits have more of the first value than the second value. Indication is made whether the bits were flipped or not flipped. Parity is calculated for the bits and the bits and the parity for the bits are written to a location in the non-volatile memory. The bits at the location in the non-volatile memory are read and each of the bits having the first value are flipped to the second value and each of the bits having the second value are flipped to the first value in response to indication that the bits were flipped.
