A method for address error check in a storage control circuit having a storage unit operable to store data in a storage area specified by an address encodes a first code assigned to the address with an even number of bits, encodes a second code assigned to the data written to the storage unit with an odd number of bits, generates a check code based on the first and second codes and stores the check code in the storage unit in correspondence with the data written to the storage unit, and conducts an error check based on data read from the storage unit, a check code corresponding to the data read, and a read address, thus detecting a multi-bit address error.
