Abstract
A semiconductor device includes: a power supply; a circuit block that has at least one storage element and operates by receiving a power supply voltage from the power supply; a power management unit that controls the power supply to change the power supply voltage; and a storage element monitor circuit that generates a first malfunction signal at a first margin voltage that is higher than a voltage at which the storage element does not normally operate in a case where the power supply voltage lowers, wherein the power management unit controls the power supply so that the power supply voltage does not become lower than the first margin voltage.
