Abstract
Disclosed is a semiconductor device that suppresses stress-induced resistance value changes. The semiconductor device includes a resistance correction circuit. The resistance correction circuit includes a first resistor whose stress-resistance value relationship is a first relationship, a second resistor whose stress-resistance value relationship is a second relationship, and a correction section that controls the resistance value of a correction target resistor. The correction section detects the difference between the resistance value of the first resistor and the resistance value of the second resistor and corrects, in accordance with the result of detection, the resistance value of the correction target resistor.
