SEMICONDUCTOR DEVICE, METHOD FOR DESIGNING SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes an electronic circuit, a setting processor, and a voltage generator. The electronic circuit includes a transistor. The setting processor changes a value of an operating voltage to be supplied to the electronic circuit from a first value to a second value smaller than the first value, according to a characteristic of the transistor. The voltage generator generates the operating voltage at a value set by the setting processor. The first value and the second value are decided in consideration of a variation in the characteristic of the transistor due to a variation in the electronic circuit during manufacture.
