Abstract
A two-dimensional array of switching devices comprises a plurality of crossbar tiles. Each crossbar tile has a plurality of row wire segments intersecting a plurality of column wire segments, and a plurality of switching devices each formed at an intersection of a row wire segment and a column wire segment. The array has a plurality of lateral latches disposed in a plane of the switching devices. Each lateral latch is linked to a first wire segment of a first crossbar tile and a second wire segment of a second crossbar tile opposing the first wire segment. The lateral latch is operable to close or open to form or break an electric connection between the first and second wire segments.
