ABSTRACT:
A power control method and power control structures are provided for managing a plurality of voltage islands of a functional chip. The power control structure includes a supply control and partition chip positioned between a substrate carrier and a functional chip including a plurality of voltage islands. The supply control and partition chip includes a plurality of first electrical connections to the functional chip including the plurality of voltage islands. The supply control and partition chip includes a plurality of second electrical connections to the substrate carrier. Power applied to predefined ones of the first electrical connections to the functional chip are selectively switched on and off by the supply control and partition chip.
