Abstract
An integrated circuit device is provided with a power supply voltage generator therein. This voltage generator is configured to respond to an operating mode control signal by generating first and second power supply voltages at equivalent voltage levels when the operating mode control signal designates a normal mode of operation within the integrated circuit device. The power supply voltage generator is also configured to reduce the first and second power supply voltages to unequal lower voltage levels when the operating mode control signal designates a power saving mode of operation within the integrated circuit device. The power supply voltage generator may also generate a third power supply voltage at a constant level during both the normal and power saving modes of operation.
