Abstract
In a semiconductor device, one ends of capacitors connected via switching elements to multiple-input terminals, the other ends of the capacitors being connected in common to an input terminal of a sense amplifier. A first power source is provided for supplying a power to the switching elements, and a second power source is provided for supplying a power to the sense amplifier. The first and second power sources are independent and separate.
Claims33
