Abstract: According to one embodiment, an error correction device includes a syndrome processing unit, a generation unit, and a search processing unit. The syndrome processing unit generates a syndrome value based on received data. The generation unit generates t (t is a maximum number of correctable bits) coefficient values of an error position polynomial based on the syndrome value. The search processing unit calculates a root of the error position polynomial, with a concurrency of computation being equal to or greater than “2”, by using the coefficient values of the error position polynomial, when a number of error bits is not more than a predetermined value s (1
