Claim Text:
1. A semiconductor device comprising: a termination resistor circuit including a first termination resistor connected to a power voltage and a second termination resistor between the first termination resistor and a ground, the first termination resistor and the second termination resistor having values that change based on a feedback signal; a mismatch detector configured to generate a compared result based on a potential difference between a voltage of a center node and a reference voltage, the center node being between the first termination resistor and the second termination resistor, a value of the reference voltage being half of the power voltage; a code generator configured to, a code register configured to generate a mismatch code, the mismatch code controlling a mismatch between the first termination resistor and the second termination resistor based on the feedback code; and a corrector configured to compensate for the mismatch between the first termination resistor and the second termination resistor based on the mismatch code, wherein,
