DECODING METHOD AND A MEMORY SYSTEM DEVICE FOR USING THE METHOD, PARTICULARLY FOR BEING MORE EFFICIENT IN AN ITERATIVE DECODING OPERATION

摘要

PURPOSE: A decoding method and a memory system device for using the method are provided to improve decoding throughput by increasing the successful rate of a decoding operation while reducing an error-floor region.;CONSTITUTION: Plural parameter nodes and plural check nodes are updated by using a provability value of the received data(S120). If the updating is not successful, at least one variable node is selected from the variable nodes. The provability value of the data received to the selected variable node is corrected. The variable nodes and the check nodes are updated by using probability values.;COPYRIGHT KIPO 2010
