Semiconductor chip, semiconductor integrated circuit using the same, and method of selecting semiconductor chip

Abstract

Semiconductor chips mounted in a laminated manner on a substrate and a semiconductor integrated circuit device using the semiconductor chips. A predetermined semiconductor chip is selected by chip selection signals from an external unit despite the chips having the same wiring pattern are laminated in a plural number one upon the other. The semiconductor integrated circuit device is fabricated by using such semiconductor chips. The semiconductor chip comprises a plurality of first electrode terminals arranged on a front surface maintaining a predetermined pitch to receive reference signals for producing comparison signals that are to be compared with chip selection signals in a comparator circuit to select a chip, a plurality of second electrode terminals arranged on a back surface opposed to the front surface each being deviated by one pitch from the plurality of the first electrode terminals to output the reference signals input to the first electrode terminals, and connection portions for electrically connecting the first and second electrode terminals that are deviated by the one pitch.
