A decoding method, a memory controlling circuit unit and a memory storage device are provided. The decoding method includes: performing a first type decoding operation for a first frame including a first codeword to obtain a second codeword. The method also includes: recording error estimate information corresponding to the first frame according to an execution result of the first type decoding operation. The method further includes: updating the first codeword in the first frame to the second codeword if the error estimate information matches a first condition; and performing a second type decoding operation for a block code including the first frame.

The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

A set of bits of a segment of a memory device that is associated with an unsuccessful first decoding operation can be identified. A discrepancy value for at least one bit of the set of bits can be calculated. It can be determined whether the discrepancy value calculated for the at least one bit of the set of bits corresponds to a correction capability of the failed decoding operation. In response to determining that the discrepancy value calculated for the at least one bit corresponds to the correction capability of the failed decoding operation, the at least one bit of the set of bits can be corrected by switching a value of the at least one bit.

Apparatuses and methods for performing an error correction code (ECC) operation are provided. One example method can include performing a first error code correction (ECC) operation on a portion of data, performing a second ECC operation on the portion of data in response to the first ECC operation failing, and performing a third ECC operation on the portion of data in response to the second ECC operation failing.

An apparatus may include a circuit configured to initialize a read operation to read one or more requested data segments of a respective data unit having a plurality of data segments. Based on a number of failed data segments of the requested data segments and an erasure capability of an outer code error correction scheme, the circuit may perform erasure recovery to recover the failed data segments. Based on the number of failed data segments, the erasure capability of the outer code error correction scheme, and a threshold value, the circuit may perform iterative outer code recovery to recover the failed data segments.

A set of bits of a data block that is associated with an unsuccessful first decoding operation may be identified. A second decoding operation to simulate switching at least one bit of the set of bits may be performed. At least one bit of the set of bits switched during the performance of the second decoding operation may be determined to correspond to an error. The error from the at least one bit of the set of bits may be corrected by changing a value of the at least one bit.

A plurality of error correction circuits corrects errors of the data transmitted through the plurality of transmission lines. A combining portion combines the plurality of transmission lines to the plurality of error correction circuits. The plurality of transmission lines includes a first transmission line, and a second transmission line having a lower transmission characteristic than the first transmission line. The plurality of error correction circuits includes a first and a second error correction circuit having lower error correction capability and power consumption than the first error correction circuit. The combining portion uses a function to combine a plurality of error correction circuits with one transmission path, combines the first transmission line with the second error correction circuit at a higher rate than the first error correction circuit, and combines the second transmission line with the first error correction circuit at a higher rate than the second error correction circuit.
