CROSSBAR SWITCH, LOGIC INTEGRATED CIRCUIT USING SAME, AND SEMICONDUCTOR DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/042750

Kind Code:

A1

Abstract:

A purpose of the invention is to provide a crossbar switch for reducing the layout areas of a crossbar switch and peripheral circuits thereof. A crossbar switch of the invention comprises: a plurality of first wires extending in a first direction; a plurality of second wires extending in a second direction; a plurality of third wires extending in a third direction; a plurality of fourth wires extending in a fourth direction; and a plurality of switch cells connected to the first and second wires. The first wires are skew relative to the second and fourth wires, while the third wires are skew relative to the second and fourth wires. The switch cells are connected to the third and fourth wires, and further, the third wires are also connected to the switch cells connected to the first wires adjacent to the respective first wires; or alternatively, further, the fourth wires are also connected to the switch cells connected to the second wires adjacent to the respective second wires.
