Abstract
A semiconductor chip includes a semiconductor substrate, terminals of A (A is an integer equal to or larger than two groups that are included in each of groups, and an integrated circuit. A plurality of terminals in each of the groups are arranged in accordance with predetermined basic terminal arrangement. Each of the A groups is disposed at each of positions that are defined by rotating one of the positions around a point. Each of the groups includes same-function terminals Vdd (Vss, OE, and WE) to achieve the same function at the same positions of the basic terminal arrangement to enable the same semiconductor chips to be stacked.
