Abstract:
1. An integrated circuit comprising: a first power domain; a second power domain; a power supply control unit for supplying a first voltage to the first power domain and a second voltage to the second power domain; a switch block that provides at least one current path between the first and second power domains during a predetermined operating mode; a first power line having the first voltage applied thereon within the first power domain, with the first power line being located within the first power domain; and a second power line having the second voltage applied thereon within the second power domain, with the second power line being located within the second power domain; wherein the switch block connects the first power line to the second power line during the predetermined operating mode, and wherein the switch block disconnects the first power line from the second power line when the integrated circuit is not in the predetermined operating mode, and wherein the first power line has the first voltage applied thereon and the second power line has the second voltage applied thereon while the first and second power lines are disconnected from each-other during the integrated circuit not being in the predetermined operating mode.
