A read-only memory apparatus is described employing a plurality of stripline-type transmission lines. The input and output transmission lines are formed by signal conductors provided on the opposite sides of a common ground plane conductor. A plurality of openings are provided through the common ground plane at some of the intersections of the input and output signal conductors and such openings are positioned to produce a digitally coded output signal on the output signal conductors when an input signal applied to the input signal conductors crosses such openings.
