    摘要: In a memory system, a memory controller includes a randomizer and a seed controller. The seed controller provides a seed to the randomizer and includes; a first register block performing a first cyclic shift operation using a first parameter related to the nonvolatile memory device, a second register block performing a second cyclic shift operation using a second parameter related to the nonvolatile memory device, and a seed generating block generating the seed from the first and second cyclic shift results.

    摘要: A method of operating a memory system including a nonvolatile memory including a memory block, and a memory controller including an erase control unit, includes performing pre-reading a plurality of memory cells connected to a selected word line of the memory block, generating an off cell count based on the pre-reading result, by operation of the erase control unit, comparing the off cell count with a reference value to generate a comparison result, and changing an erase operation condition based on the comparison result, by operation of the nonvolatile memory, and erasing the memory block according to the changed erase operation condition.

    摘要: A method may be provided to detect and correct data errors in a data system where a data message has been encoded with outer parity bits based on the data message using an outer encoding technique to provide an outer codeword and with inner parity bits based on the outer codeword using an inner encoding technique different than the outer encoding technique to provide an inner codeword. The method may include using the inner parity bits and an inner decoding technique corresponding to the inner encoding technique to perform inner decoding of the inner codeword. Responsive to performing inner decoding of the inner codeword without error, the data message may be extracted from a result of inner decoding the inner codeword without using the outer parity bits to decode the result of inner decoding the inner codeword. Related systems are also discussed.
