Patent abstract
An object of the present invention is to provide a technique of duplexing monitor circuits in which a common cause failure can be eliminated. A semiconductor device has: a first monitor circuit monitoring that temperature or voltage of the semiconductor device is within a normal operation range; and a second monitor circuit monitoring normal operation of the first monitor circuit. The first and second monitor circuits generate information of temperature or voltage on the basis of different principles.
