Abstract
A memory system includes a non-volatile memory and a memory controller. During a read operation to read data stored in the non-volatile memory as an N-dimensional error correction code, where N is two or more, the memory controller performs an error correction process on the N-dimensional error correction code iteratively, the error correction process including a first decoding process on a first decoding input to produce a first decoding output and a second decoding process on a second decoding input to produce a second decoding output. During the error correction process, upon determining that errors remaining in the second decoding output after a most recent iteration would not be correctable, the memory controller performs a next iteration using a first decoding input for the next iteration, which is a modified form of the second decoding output of the most recent iteration.
