A latency counter includes a counter circuit and a point-shift FIFO circuit. Latch circuits included in the point-shift FIFO circuit are divided into n groups having wired-OR outputs, and an output of a latch circuit that belongs to a group different from a current group is selected each time a count value is updated.
