Abstract
A nonvolatile memory device includes a data generating unit for generating a first reference value randomly or pseudo-randomly according to a first program request to program data in a memory cell, a seed selecting unit for selecting at least one of a plurality of seeds using the first reference value, and a randomizer for generating randomized data by using the selected seed. The data generating unit regenerates the first reference value as a second reference value different from the first reference value when a second program request is made, and the seed selecting unit selects another seed using the second reference value.
