摘要: An operating method of an error correction decoder includes receiving data, setting initial log-likelihood values of variable nodes, and decoding the received data by updating a log-likelihood value of a selected variable node by use of a minimum value and a minimum candidate value associated with the selected variable node. The minimum value indicates a minimum value of absolute values of log-likelihood values of first variable nodes sharing a check node with the selected variable node and including the selected variable node. The minimum candidate value indicates one from among absolute values of log-likelihood values of second variable nodes that has the smallest value greater than the minimum value. The second variable nodes are selected later than one from among the first variable nodes corresponding to the minimum value.

摘要: A decoder includes multiple decoder stages and a controller. The decoder stages perform decoding operations with respect to a received signal using corresponding different decoding algorithms. The controller determines whether the decoding operation performed by one of the decoder stages with respect to the received signal is successful, and controls the decoding operation of each of the other decoder stages in response to a result of the determination.

摘要: A method of decoding data of a non-volatile memory device is provided. The method includes a first decoding operation of reading first hard decision data from the non-volatile memory device using a first hard decision read level and performing decoding using the first hard decision data; a second decoding operation of reading first soft decision data from the non-volatile memory device when the decoding fails in the first decoding operation, and performing decoding using the first soft decision; and a third decoding operation of changing from the first hard decision read level to a second hard decision read level when the decoding fails in the second decoding operation, reading second hard decision data using the second hard decision read level, and performing decoding either using the second hard decision data or using both the second hard decision data and the first soft decision data.

摘要: An iterative decoding method is disclosed and includes sequentially executing a number of iterative decoding cycles in relation to a parity check equation until the parity check equation is resolved, or a maximum number N of iterative decoding cycles is reached, during execution of the number of iterative decoding cycles, storing in a data buffer minimum estimated values for a set of variable nodes corresponding to a minimum number of bit errors, and outputting the minimum estimated values stored in the data buffer as a final decoding result when the number of iterative decoding cycles reaches N.
