Patent ID: 7499041

Claim:
An integrated circuit device comprising: an interface circuit block that transfers data through a serial bus using differential signals, when a direction from a first side which is a short side of the interface circuit block to a third side opposite to the first side is defined as a first direction and a direction from a fourth side which is a long side of the interface circuit block to a second side opposite to the fourth side is defined as a second direction, the interface circuit block including: a circuit formation area in which a circuit which performs given processing is formed, an input terminal formation area which is disposed on a side of the circuit formation area in the second direction and in which a plurality of input terminals are provided on the second side along the first direction, and a plurality of power supply lines for the integrated circuit device formed to extend along the first direction in the input terminal formation area in a first interconnect layer in a lower layer of a second interconnect layer in which the input terminals are formed.
