Zusammenfassung: | The purpose of the present invention is to provide a method for performing low density parity check (LDPC) decoding in a memory system, which improves memory access scheduling in a decoding process. A method for performing LDPC decoding in a memory system and an LDPC decoder using the same are disclosed. The method for performing LDPC decoding in a memory system comprises the steps of: exchanging messages between check nodes and variable nodes based on scheduling information that indicates a message exchange order between the check nodes and the variable nodes for LDPC decoding; and performing LDPC decoding based on the exchanged messages, wherein the scheduling information is determined by an order control of the check nodes or an order control of the variable nodes from an LDPC bipartite graph. |
