Abstract

Various systems and methods for power reduction are disclosed herein. As one example, a method for power reduction in a semiconductor device is disclosed. The method includes providing a semiconductor device that includes a bus. The bus includes a group of signals and a control signal associated with the group of signals. In one particular case, the group of signals is a data bus and the control signal is a low frequency signal implementing some particular control specific to the bus. In the method, the control signal doubles as a polarity control that indicates a polarity state of the group of signals while actively indicating the status of the particular control.
