Abstract
A method of responding to a read request from a host includes: obtaining read data from a memory device, performing first iteration ECC decoding on the read data to generate a plurality of pieces of decoded data, selecting one of the plurality of pieces of decoded data as intermediate data as intermediate data, generating preprocessed data based on the read data and the intermediate data and performing second iteration ECC decoding on the preprocessed data when the first iteration ECC decoding fails, and outputting the intermediate data to the host when the first iteration ECC decoding succeeds.
