ABSTRACT:
A novel semiconductor device having two different power circuits is disclosed. Even if the output of the stage before a voltage conversion circuit declines due to the decline of the level of the power circuits or the voltage drop through a resistor, the voltage conversion circuit performs a normal operation. The semiconductor device comprises a first power circuit for generating a first source voltage, a second power circuit for generating a second source voltage higher than the first source voltage, and a second power level detection circuit for detecting the second source voltage. The first power circuit changes the first source voltage in accordance with the result of detection by the second power level detection circuit.
