Patent abstract

A nonvolatile memory array includes two or more devices, each device containing data that is scrambled using a different scrambling scheme. When the same data is provided and stored in both devices, different data patterns occur in each device, so that if one of the patterns causes data pattern induced errors, the original data can be recreated from another copy that does not share the same data pattern.
