Claim 2:
3. The semiconductor device according to claim 1, wherein
the reference voltage circuit comprises: a control terminal; a memory circuit comprising an output port outputting an adjustment code signal of N bits taking a natural number N as an adjustment bit number; a common mode potential terminal; an output terminal; a current source comprising an output port connected to the output terminal; a resistor comprising a first port connected to the common mode potential terminal, and a second port connected to the output terminal; and a decoder which comprises an output port outputting a resistance control signal and generates the resistance control signal according to the adjustment code signal and the control signal received at the control terminal of the reference voltage circuit, wherein
the resistor is a variable resistor in which, based on the resistance control signal containing a first logic or a second logic, a resistance value is controlled to a reference resistance value in response to receiving the resistance control signal which is the first logic, and the resistance value is controlled to a resistance value different from the reference resistance value in response to receiving the resistance control signal which is the second logic.
