Abstract
A semiconductor chip including an internal circuit, a plurality of electrode pads and a plurality of I/O cells. The plurality of electrode pads are arranged on a first line, a second line and a third line. Each of the plurality of electrode pads arranged at least on the first and second lines overlaps corresponding one of the plurality of I/O cells in a plan view. The plurality of I/O cells are provided on a peripheral region of the semiconductor chip. Each of the plurality of I/O cells includes a protective circuit, and is connected to corresponding one of the plurality of electrode pads. The protective circuit includes a power source-side protective circuit provided between the corresponding one of the plurality of electrode pads and a power source wiring; and a ground-side protective circuit provided between the corresponding one of the plurality of electrode pads and a ground wiring.
