Abstract
A method of performing a cyclic redundancy check (CRC) operation in a memory system, and a memory controller that uses the same. The method includes initializing a linear feed-back shift register (LFSR) circuit in a CRC polynomial, generating CRC parity information with respect to input data to be stored in a memory device by using the LFSR circuit, and generating a CRC code with respect to the input data based on the CRC parity information, such that the initialization of the LFSR circuit is set such that a register initial value of the LFSR circuit is determined to satisfy a condition that, when data input to the LFSR circuit is first state information, the CRC parity information generated from the LFSR circuit is second state information.
