Abstract
A memory system may include a memory core; and an ECC engine configured to, during a write operation, perform a logical operation on an M-bit write data and an H matrix, and generate an N-bit first error correction code and an N-bit second error correction code to be stored in the memory core together with the write data, where N is an integer of 2 or more and M is a multiple of N. The H matrix may include an upper matrix having a size of N*(M+2N) and a lower matrix having a size of N*(M+2N), the lower matrix may include M/N Tcompanion matrices each having a size of N*N, and k of the Tcompanion matrices may have values which are positive integers different by N or more for each companion matrix.
