PURPOSE:To accomplish collective wiring with an automatic wiring tool by channel router by a method wherein the region of a memory circuit integrated with cell arrays is used as the second and third layer metallic wiring regions. CONSTITUTION:Part of the cell arrays are shorter than the other, and the shorter part is provided with the memory circuit 4 in the remaining space. Besides, an input and output circuit 3 is formed in the periphery of the chip. The connection between elements in the arrays 1 is carried out with the first layer metallic wiring, and the connection between elements in the circuit 4 is carried out likewise with the first layer metallic wiring. The connection between arrays and between arrays 1 and the circuit 4 is carried out with the second layer metallic wiring and the third layer metallic wiring. |
