A control device for controlling an electro-optic modulator which receives an optical input signal, modulates the optical input signal with an electrical input signal and a bias voltage signal, and outputs the modulated optical signal is provided. The anode is formed from a plurality of separate components, which allows the properties of each component to be more readily controlled during manufacturing. Various additional embodiments are described having an array architecture such that two memory cells sharing the same bit line also share the same program line. The limb rest is comprised of a pair of extension arms pivotally attached to the body, upright arms projecting from each extension arm and a stop.
