Abstract
A decoding device for decoding a product code and a decoding method using the same are provided. The decoding device comprises an erasure flag processor, a decoder and a confidence flag processor. The erasure flag processor determines to set a particular value or a non-particular value for each erasure flag according to a plurality of the confidence flags, wherein each symbol has a confidence flag and an erasure flag correspondingly and each confidence flag has a confidence flag value. The decoder is coupled to the erasure flag processor to correct the symbols according to the erasure flags and outputs the corrected symbols. The confidence flag processor is coupled to both the erasure flag processor and the decoder to reset the confidence flag values of the confidence flags according to the erasure flags and the corrected symbols.
