An address control device changes the internal address corresponding to the address at which an error occurred to a new address if an error is detected in a data word during a read from a main memory device. The address control device specifies a different memory area during subsequent data writes and does not use the memory area in which the previous error occurred. Moreover, if the error detection device detects an error while a data word is read from the main memory device, a correction device corrects the data word.
