Abstract: A low-density parity check (LDPC) decoder may include a variable node processing unit and a check node processing unit. The check node processing unit includes memory elements storing a check node value. The memory elements are interconnected through two or more paths, and each of the paths may include a total or partial cyclic permutation of the memory elements to transmit the check node value.

Abstract: A method of operating a memory device including a plurality of memory cells is provided. The method includes receiving a first write command, determining whether a target memory cell is deteriorated or not, in response to the first write command, and writing the second data by selectively erasing the target memory cell according to a result of the determination and by programming the target memory cell.
