Abstract
An apparatus includes micro-electromechanical (MEM) devices, a charge source, and a discharge mechanism. Each MEM device has different states based on a charged induced thereon. The charge source is to induce the charge thereon such that the MEM devices each enter one of the different states thereof. The discharge mechanism for the MEM devices is to discharge the induced thereon. The discharge mechanism includes one of a resistor for each MEM device and an ultraviolet (UV) light source. The resistor is to discharge the charge on its MEM device to ground. The UV light source is to emit photons onto the MEM devices, such that the photons discharge the charge on the MEM devices via photoelectric effect.
