Abstract
A method in which data is randomized before being stored in a non-volatile memory to minimize data pattern-related read failures. Predetermined randomized non-user data is stored in a block or other location of a memory array, and accessed as needed by a memory device controller to randomize user data before it is stored in other blocks of the array. Each portion of the user data which is stored in a block is randomized using a portion of the non-user data which is stored in the same relative location in another block.
