ABSTRACT:
A system for reducing power in electronic systems blocks current paths by electrically isolating idle, targeted devices through switching off the various device's entire sets of pins from the rest of the electronic system. Solid state switches are connected to every pin of a targeted device. In one logic state a control signal will turn the switches on and thereby connect the targeted device to the remainder of the system. In another logic state, the control signal will isolate the targeted device.
