A memory system includes a non-volatile memory and a memory controller. The memory controller is configured to read data from the non-volatile memory, obtain a plurality of decoded words based on a syndrome calculated from a soft decision input data based on the read data, calculate a plurality of metrics for the plurality of decoded words, generate a metric array using the calculated metrics. Further, the memory controller is configured to, based on a relationship of each value of the metric array with a smallest one of the metrics and a second smallest one of the metrics, obtain a soft decision output data corresponding to the soft decision input data.
