Abstract

PURPOSE:To simplify the hardware and increase the controllability of an inspection, by carrying out the inspection of information with every desired block but with every unit information. CONSTITUTION:The value obtined by subtracting the value obtained by adding all pieces of information of an information part 1 of a nonvolatile storage circuit from the specifice information of ''all 0'', ''all 1'', etc. is set at a switch information part 21. All pieces of information of the part 1 are successively supplied to an arithmetic control circuit 3 via a data bus 7 and by the signals of an address bus 5 and a control bus 6 which are supplied from the circuit 3, and thus added together. After this, the information of the part 21 is supplied to the circuit 3 via the bus 7, and the switch information is added to the added data. If all added data are used as the specific information, it is decided that the information of the part 1 is correctly stored. If not, it is known that an error is caused to the information stored at the part 1.
