A turning structure for routing channels in a field programmable gate array, comprising a first plurality of routing channels having a first direction and a second plurality of routing channels having a second direction. The first plurality of routing channels intersects the second plurality of routing channels to form a plurality of matrices of intersecting interconnect conductors in the routing channels. A first number of reprogrammable elements is disposed at intersections in at least one of the plurality of matrices, a second number of reprogrammable elements disposed at intersections in at least one of the plurality of matrices. The second number of reprogrammable elements is greater than the first number of reprogrammable elements, and a third number of reprogrammable elements disposed at intersections in at least one of the plurality of matrices. The third number of reprogrammable elements is greater than the second number of reprogrammable elements.
