Abstract
A multiple power supply semiconductor device includes a first semiconductor circuit for transferring signals with a signal level of a first voltage, a second semiconductor circuit for transferring signals with a signal level of a second voltage lower than the first voltage, a level shifter for converting a level of an output signal from the second semiconductor circuit to a third voltage higher than the first voltage, and a circuit for further converting the level of the signal whose level is converted to the third voltage to the first voltage to be supplied to the first semiconductor circuit. This makes it possible to implement a multiple power supply semiconductor device with low power consumption and small hardware volume.
