A power line control circuit of a semiconductor device in which a width of a power line can be selectively controlled. The power line control circuit of the semiconductor device according to the present invention can selectively control the width of the power line employing the dummy power line. It is therefore possible to easily change the width of the power lines and to reduce the manufacturing cost and the manufacturing time depending on the formation of the power lines. Furthermore, the power line control circuit of the semiconductor device according to the present invention can selectively control the width of the power lines, if appropriate. Accordingly, mesh of optimized power lines can be provided. Furthermore, more stabilized product characteristics can be secured and the yield of semiconductor memory devices can be enhanced. In addition, the power line control circuit of the semiconductor device according to the present invention can selectively change power mesh corresponding to a power line method or operation mode of a product.
