A system comprises transceiver logic that receives signals on each of an array of frequencies. A conductive film is formed over interior surfaces of the nanochannels, and a charge barrier is formed over the conductive film. When transitioning from the full density mode to the half density mode, data are copied from each row of memory cells storing data to an adjacent row of memory cells. A first polarization direction changing means is adhered to a first face of the polarized light separation means in the first viewing region.
