Semiconductor devices

Abstract

A semiconductor device is provided capable of performing operations on two different functions. The semiconductor device includes first and second current generating circuits, a current source, and wiring. The first current generating circuit includes a first input terminal and a first output terminal; the second current generating circuit includes a second input terminal, a third input terminal, and a second output terminal; and the current source includes a third output terminal. The first output terminal is connected to the second input terminal and the wiring, and the third input terminal is connected to the third output terminal. The first current generating circuit has the function of generating a second current flowing through the first output terminal as a mirror function, referencing a first current flowing through the first input terminal. The current source has the function of causing a fourth current to flow through the third output terminal. The second current generating circuit has the function of generating a fifth current flowing through the second output terminal as a mirror function, referencing the smaller of the difference between the second current and the third current flowing through the wiring, and the fourth current.
