Abstract
A power management apparatus that controls the use of power within an integrated circuit. A first embodiment gates integrated circuit power on or off concurrently with switches inserted between the co-resident functional circuit I/O nets and the integrated circuit I/O pads. A second embodiment instantiates the power management apparatus on an integrated circuit by itself for connection to external integrated circuits. Buffering or sequencing is provided for both embodiments.
