Abstract
An error correcting method of a memory system includes: reading data and an error correction code from a plurality of memory chips; correcting an error of the data based on the error correction code; determining whether or not a miscorrection occurs in the correcting of the error of the data; designating one memory chip among the plurality of the memory chips as a chip-killed memory chip when a miscorrection occurs; re-correcting the error of the data based on the error correction code in consideration of the designated chip-killed memory chip; and re-determining whether a miscorrection occurs in the re-correcting of the error of the data.
