PURPOSE:To make it possible to cope with favorably to a modification of an arrangement pitch between pads by a method wherein a number of input/output cells per one piece of a pad is set according to the arrangement pitch. CONSTITUTION:A number of input/output cells 13a, 14b..., which are parallel- connected per one piece of a pad, is set according to an arrangement pitch between pads 14a, 14b... Accordingly, a readjustment of the design of the input/ output cells becomes unnecessary at the time of modification of the arrangement pitch between the pads and moreover, a load driving power can be selected according to the need without changing the size of a chip main body. |
