Abstract: An integrated circuit (IC) chip provided with a ‘power-save’ switch, including MEMS (Micro-Electro-Mechanical Systems) switches in each power and ground ring, to be used to open the circuit and eliminate power drain. The MEMS switches preferably include a cantilevered beam deflected by an electrostatic charge. When the equipment of which the IC forms a part is put on standby, it enters a low-power mode in which the ‘power-save’ switch in each IC is actuated by a small control circuit that remains powered up. The MEMS switches are preferably latched into position at least when in the open position, for example by using an permanent magnet, so that no power is consumed by the open switches. The invention is applicable to chips used in wireless mobile terminals, where power consumption is critical, and in any application where it is necessary to enter a standby mode between uses.
