Abstract

Apparatus and methods are disclosed, such as those involving a flash memory device. One such apparatus includes a memory block including a plurality of memory cells; and a data randomizer configured to randomly or pseudo-randomly change original data to be stored in the memory block to changed data. The original data is changed such that a pattern of data as stored in the memory block is different than what it would have been if the original data had been stored in the memory block during a write operation. This configuration can reduce or eliminate data pattern-dependent errors in data digits stored in memory cells.
