Abstract
Systems, devices, and methods for decoding information bits obtained from storage, including obtaining a frame corresponding to a codeword from the storage device, performing a first decoding operation on the frame, based on the first decoding operation indicating that a number of errors is greater than a predetermined number, selecting at least one potential error bit, and perform a second decoding operation based on the at least one potential error bit, based on the second decoding operation indicating that the number of errors is not equal to the predetermined number plus one, determining that the frame is not correctable by the first decoding operation and the second decoding operation, and based on the second decoding operation indicating that the number of errors is equal to the predetermined number plus one, correcting the frame based on a result of the second decoding operation to obtain a corrected frame, and obtaining information bits corresponding to the codeword based on the corrected frame.
