Claim 10:
11. A semiconductor module, comprising:
a memory device configured to store data;
a controller configured to control the memory device;
a circuit board on which the memory device and the controller are mounted; and
a first differential signal transmission circuit formed on the circuit board to connect the controller and the memory device, the first differential signal transmission circuit including a plurality of input wiring patterns and a plurality of complementary wiring patterns, alternately arranged on an upper surface and a lower surface of an insulating layer, wherein:
the plurality of input wiring patterns are connected to a common input wiring pattern at opposite ends of the first differential signal transmission circuit,
the plurality of complementary wiring patterns are connected to a common complementary wiring pattern at the opposite ends of the first differential signal transmission circuit, and
wherein, among the plurality of input wiring patterns and the plurality of complementary wiring patterns, line widths of wiring patterns on the upper surface of the insulating layer are different from line widths of wiring patterns on the lower surface of the insulating layer.
