Abstract: The inventive concepts relate to an operation method of an error correction decoder correcting an error of data read from a nonvolatile memory. The operation method may include receiving the data from the nonvolatile memory, performing a first error correction with respect to the received data in a simplified mode, and performing, when the first error correction fails in the simplified mode, a second error correction with respect to the received data in a full mode. When the first error correction of the simplified mode is performed, a part of operations of the second error correction of the full mode may be omitted.

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.
