Abstract
A counted value storage system includes a non-volatile memory for successively storing a counted value in one of a plurality of memory areas assigned with addresses, and a control unit coupled to the non-volatile memory for controlling the address where the counted value is stored in the non-volatile memory, where the control unit includes the functions of circulatively designating the address from a smallest address and storing a predetermined data in the non-volatile memory at an address which is one greater than an arbitrary address where a most update counted value is stored. The address where the predetermined data is stored indicates an address where a next counted value is to be stored, and the predetermined data indicates a value which is greater than a maximum value of a counted value which is stored in the non-volatile memory.
