Abstract
A semiconductor device has a first chip and a second chip sealed in a single package. The first chip includes a regulator which generates an internal voltage from a supply voltage, a reset circuit which monitors the supply voltage and the internal voltage to generate a reset signal, and a controlled circuit which operates by being supplied with the supply voltage. The second chip includes a controlling circuit which generates a control signal for the controlled circuit by being supplied with the internal voltage. The reset signal is fed to both the controlling circuit and the controlled circuit.
