Abstract
A nonvolatile power management apparatus that controls the use of power within an integrated circuit. The embodiment varies the power applied to a functional circuit within the integrated circuit. At nominal power, the functional circuit operates normally per nominal operational specifications. Under reduced power, the integrated circuit retains all of its internal states, but has its I/O nets isolated from external circuitry. This prevents latch-up of the functional circuit operating from reduced power (low power input voltage) and prevents external circuitry connected to the integrated circuit from being overloaded.
