Abstract
A random data reading method of a nonvolatile memory device includes receiving an initial seed corresponding to a selected page of the nonvolatile memory device and relative location information of read-requested random data in the selected page. The method further includes generating a seed for randomizing the random data by subjecting the initial seed and the location information to a finite field arithmetic operation, and de-randomizing the random data based on a random sequence generated from the seed.
