Abstract
Abstract There is disclosed a gas discharge device having an inherent memory wherein all electrically operative elements are formed on a common support substrate. The device comprises a monolithic panel structure in which the conductor arrays are created on a single substrate and wherein two or more arrays are separated from each other and from the gaseous medium by at least one insulating member. In such a device the gas discharge takes place not between two opposing members, but between two contiguous or adjacent members on the same substrate.
