Abstract
A non-volatile memory in which data is randomized before being stored in the non-volatile memory to minimize data pattern-related read failures. Randomizing is performed using circuitry on the memory die so that the memory die is portable relative to an external, off-chip controller. Circuitry on the memory die scrambles user data based on a key which is generated using a seed which is shifted according to a write address. Corresponding on-chip descrambling is also provided.
