Abstract

According to one embodiment, a decoding device that decodes a multi-dimensional error correction code having two or more component codes includes a storage unit that stores therein the multi-dimensional error correction code, an additional-information storage unit that manages each syndrome of the at least two component codes or a reliability flag indicating whether the syndrome has a value of 0 or other than 0, a decoder that performs a first decoding process in a unit of component code with respect to the multi-dimensional error correction code stored in the storage unit to detect an error vector of each component code, and a detection unit that determines whether detection of the error vector by the decoder is false detection, based on the syndrome or the reliability flag stored in the additional-information storage unit.
