To provide a counter device capable of reducing a mounting space and raising a density.

This counter device is provided with a generated event selection part 1 for specifying the corresponding address of a memory 2 for respective generated events (1-N), the memory 2 provided with an area for storing count values for the respective generated events (1-N), a memory control part 3 for controlling the read/write of the memory 2, reading the counter value corresponding to the generated event stored in the memory 2 every time the respective events are generated and rewriting the count value of the memory 2 every time the count value is updated by an addition circuit 4 to put it concretely, the addition circuit 4 for increasing and updating the count value read by the memory control part 3 every time the respective events are generated and outputting it to the memory 2 and a counting control processing part 5 for outputting write/read request signals to the memory control part 3 and inputting the counter value stored in the memory 2.
