Abstract: A decoder including a main memory, a flag memory and a decoding logic is provided. The flag memory is configured to store flag data and the decoding logic configured to perform an iteration. Further, the decoding logic is configured to: perform an ith operation using first data, wherein i is a natural number, flag-encode second data that is results obtained by performing the ith operation on the first data, store results obtained by performing the flag encoding on the second data in the flag memory as first flag data if the flag encoding succeeds, and store predetermined second flag data that is different from the first flag data of the second data in the flag memory if the flag encoding fails.

Abstract: A memory controller and an operation method thereof are provided. The operation method includes storing a plurality of random sequences, selecting at least one random sequence among the plurality of random sequences according to a data pattern of a data block, and performing conversion by at least one of randomizing the data block using the selected at least one random sequence and derandomizing the randomized data block using the selected at least one random sequence.
