Abstract
According to the present invention, an apparatus having a plurality of independently operable and powerable devices is disclosed. The apparatus includes a plurality of power rails, a plurality of ground planes, and a power management circuit. One of the power rails is associated with one of the plurality of independently operable devices. One of the plurality of ground planes is selectively associated with one or more of the plurality of power rails. The power management circuit couples to the plurality of power rails and the second plurality of ground planes, for selectively deactivating at least one of the plurality of ground planes independently of any of the other plurality of power rails.
