ABSTRACT:
In a semiconductor device in which one terminal of each of plural capacitors is connected to a corresponding multiple input terminal via a switch, and the other terminals of the capacitors are commonly connected to a sense amplifier, the other terminal of at least one capacitor is commonly connected to the sense amplifier via a second switch, thereby reducing circuit scale, increasing operation speed, improving operation precision, and saving power.
