摘要

A counting apparatus comprising an execution detection circuit for detecting the execution of a predetermined operation; plural memory circuits for commonly storing the information on the number of execution at each detection of the execution; a destruction detection circuit for detecting, at the storage of the information, whether the information stored in each memory circuit is destructed; and a correction circuit adapted, upon detection that the information of a memory circuit is destructed, to correct the destructed information with the information of another memory circuit.
