    摘要: A method of reading multi-bit data stored in a memory cell of a flash memory includes attempting to perform hard decision (HD) decoding on output data from the flash memory, and performing soft decision (SD) decoding on the output data when the HD decoding cannot be performed. The performing of the SD decoding includes: changing a maximum number of iterations according to a threshold voltage distribution of the memory cell; and performing the SD decoding based on the changed maximum number of iterations.

    摘要: 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.
