Abstract: A method of operating a decoder, which has variable nodes and check nodes, includes receiving variable-to-check (V2C) messages from the variable nodes using a first check node among the check nodes. The number of messages having a specific magnitude among the V2C messages is counted. The magnitude of a check-to-variable (C2V) message to be transmitted to a first variable node, among the variable nodes, is determined based on the count value and the magnitude of a V2C message of the first variable node.

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 device includes an input unit configured to receive a plain text and output plain blocks and CTS plain block, a multi-core unit including a plurality of encryption/decryption cores configured to encrypt each of the plain blocks provided from the input unit and output cipher blocks in accordance with control of an encryption/decryption core control unit, a CTS core unit including a CTS core configured to encrypt the CTS plain block provided from the input unit into a CTS cipher block, and an output unit configured to receive the cipher blocks and the CTS cipher block and output a cipher text. The CTS plain block is generated through a CTS calculation based on the plain text.
