PROBLEM TO BE SOLVED: To provide an error correcting device capable of outputting data whose scramble is surely released even when ECC processing is discontinued halfway. SOLUTION: The access occupancy period of a memory in a PI direction which is needed for ECC processing is shorter than that of a PO direction because addresses do not continue in the PO direction while addresses continue in the PI direction of an error correction block. Therefore, EDC/descramble processing is performed most preferentially while ECC processing in the PI direction is performed so that the EDC/descramble processing can surely be finished within an ECC processing period.
