Abstract
According to the present invention, for a module in which a plurality of integrated circuit devices are mounted in parallel, the inductance generated by the unit length of a branched signal line on a motherboard is so set that it is smaller for a branched signal line a longer distance from its branching point to its distal end, and is so set that it is larger for a branched signal line having a shorter distance from its branching point to its distal end, so that the time required for transmission of a signal from the branching point to the distal end of each branched signal line is the same.
