Abstract
An aging device according to an embodiment of the present invention includes a semiconductor substrate, first and second diffusion layers provided in a first element region, a floating gate provided above a channel region between the first and second diffusion layers, and a control gate electrode provided beside the floating gate with an interval in the lateral direction. A coupling capacitance between the floating gate and the control gate electrode is larger than a coupling capacitance between the floating gate and the semiconductor substrate.
