A memory system includes a memory device including memory sets and a controller including a decoder. The decoder receives multiple codewords from the memory sets and decodes the multiple codewords. The decoder determines an inter-set delay for a codeword of a select memory set. When the inter-set delay is greater than a maximum inter-set delay, the decoder determines a total decoding time based on an effective inter-set delay and an effective decoding time. The decoder outputs the decoded codeword at the end of the total decoding time.
