Abstract
In a nonvolatile memory array, such as a three-dimensional array of charge-storage memory cells, data is randomized so that data of different strings along the same bit line are randomized using different keys and portions of data along neighboring word lines are randomized using different keys. Keys may be rotated so that data of a particular word line is randomized according to different keys in different strings.
