Abstract
A semiconductor device may include 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, a value of the first termination resistor and the second termination resistor changes based on a feedback signal; a mismatch detector may generate a compared result based on a potential difference between a voltage of a center node, between the first and second termination resistors, and a reference voltage; a code generator may generate the feedback signal based on the compared result, and generate a feedback code based on the compared result; a code register may generate a mismatch code controlling a mismatch between the first and second termination resistors based on the feedback code; and a corrector may compensate for the mismatch between the first and second termination resistors based on the mismatch code.
