Parity check matrix generator, operating method thereof and error correction circuit using parity check matrix generated by the same

Abstract

A parity check matrix generator for generating a parity check matrix including non-binary cyclic permutation matrices may include: a first memory configured to store a first weight as location information on a non-binary cyclic permutation matrix within the parity check matrix; a second memory configured to store a second weight as cyclic strength of matrix elements of the non-binary cyclic permutation matrix; a third memory configured to store a third weight used to determine a size of a non-binary matrix element among the matrix elements of the non-binary cyclic permutation matrix; and a matrix generator configured to generate the non-binary cyclic permutation matrix by applying a non-binary value to matrix elements of 1's among matrix elements of a binary cyclic permutation matrix having a size corresponding to the non-binary cyclic permutation matrix and reflecting one or more of the first to third weights into the non-binary value.
