Three-dimensional storage system wherein all storage positions are selectably accessible. An information storage system is provided having conductor paths arranged in three spatial directions. The electrically conductive junctions formed at each intersection of three mutually perpendicular conductor paths provide the respective storage positions. All conductor path systems which terminate in a common column at one exterior surface of the system and all conductor paths terminating in a common row each have a single common selecting line and two of these mutually perpendicular selecting lines respectively form an electronic gate which acts as a switch between the conductor path ends and the storage system. All ends of the conductor paths in the same plane lie at a one constant potential and the ends of the conductor paths in other planes lie at a different constant potential.
