Abstract

A crossbar switch includes a plurality of first wires extending in a first direction and second wires extending in a second direction. The switch includes third wires extending in a third direction and fourth wires extending in a fourth direction. The switch includes switch cells connected to the first and second wires. The first wires are skewed relative to the second and fourth wires, while the third wires are skewed relative to the second and fourth wires. The switch cells are connected to the third and fourth wires, and the third wires are also connected to the switch cells connected to the first wires adjacent to the respective first wires, or alternatively the fourth wires are also connected to the switch cells connected to the second wires adjacent to the respective second wires.
