Abstract
An operation method of a decoder may include: performing a first sub-decoding operation on a target data chunk; performing a second sub-decoding operation on candidate chunks and a chip-kill chunk; performing a third sub-decoding operation to determine a global check node; performing a fourth sub-decoding operation to infer and update local variable nodes of the target data chunk and local variable nodes of a data chunk from the global check node; and repeating the first to fourth sub-decoding operations once by a set number of times based on components of the updated local variable nodes.
