Patent ID: 7904838

Claim:
An integrated circuit comprising: a core-logic providing a core-logic output; an isolation circuit in communication with said core-logic, operable to selectively provide an output corresponding to one of said core-logic output and a predetermined value; a latch interconnected to said isolation circuit, receiving said output of said isolation circuit; a power consumption controller in communication with said core-logic, said latch and said isolation circuit, said controller operable to transition said core-logic to a low power state, and prior to transitioning to said low power state: control said latch to store a value of said core-logic output and provide a corresponding output; control said isolation circuit to provide an output corresponding to said predetermined value, at said output of said isolation circuit; and said power consumption controller further operable to transition said core-loqic to a high power state; control said isolation circuit to provide an output corresponding to said output of said core-logic in said high power state; initialize said core-logic; after initializing said core logic, control said latch to provide an output corresponding to said output of said isolation circuit.
