Abstract
A memory system includes a memory device and a controller. The memory device outputs a codeword read from plural memory cells in response to a request. The controller is configured to establish a plurality of variable nodes and a plurality of check nodes from the codeword, perform a second flipping function operation for estimating flipping necessity and flipping frequency regarding the plurality of variable nodes based on the plurality of check nodes, determine, based on the flipping necessity and the flipping frequency, which iterative operation is performed during a first flipping operation for decoding the codeword, and perform the first flipping operation through a determined iterative operation to obtain the plurality of variable nodes.
