To reduce a power consumption in an always-on counter circuit.

A counter circuit has a first counter of m bits which counts values of a predetermined bit width to be stored according to an input clock, a clock transmission control circuit controlling whether or not the input clock is transmitted based on a value output according to the result of the first counter, and a second counter of n bits which counts values of the predetermined bit width to be stored according to the input clock transmitted from the clock transmission control circuit.
