Abstract
A method and apparatus to provide a power segmentation architecture that substantially eliminates the routing and area penalties associated with conventional power segmentation architectures. Power switching components are configured within the external interconnect portion of the integrated circuit (IC) to reduce the number of inter-layer interconnects that must be traversed in order to programmably supply operational power to the various device segments of the IC. A system-in-package (SIP) integration approach is alternately taken, whereby the power switching components utilized within the power segmentation architecture are conveniently allocated among the base or stacked die to reduce the number of inter-layer interconnects. The power switching components may also be implemented off-chip as discrete switching components such as a transistor or a micro-miniature switch/relay.
