A low-density parity check (LDPC) decoder includes a memory configured to store multiple variable node LLR values in a LLR memory and multiple check nodes messages in a CN memory. The LDPC decoder also includes a saturation indicator configured to determine whether each check node of the H-matrix becomes saturated, and a multiplexer. The multiplexer is configured store an extrinsic check node value in the CN memory and updated LLR value in the LLR memory when the variable node is not saturated; and store a freeze input value in the CN memory and a freeze value in the LLR memory when the variable node is saturated.
