A semiconductor device of an embodiment includes an ECC decoding processing circuit configured to perform ECC decoding on ECC frame data in a lateral direction of a product code frame, an RS decoding processing circuit configured to perform Reed-Solomon (RS) decoding on second frame data in a longitudinal direction of the product code frame, a memory Min which a syndrome generated for the ECC frame data decoded is stored, a memory Min which an RS syndrome generated for ECC frame data for which the ECC decoding has been successful is stored, and a memory D in which ECC frame data for which the ECC decoding has been failed is stored as frame data which cannot be corrected through decoding, and frame collection processing, and iterative correction processing of performing RS decoding on the uncorrected frame data collected in the frame collection processing are executed.
