Abstract
Abstract A semiconductor memory device (1) comprising a supporting board (3), a plurality of semiconductor IC chips (4) arranged on the supporting board, in which interconnection is provided between the semiconductor chips and between the semiconductor chip and the supporting board. On the portion of the upper surface including the active area, of the semiconductor chip such as a memory IC chip bonding electrodes are arranged so as to extend substantially toward the confronting side. A plurality of such a memory IC chip are arranged on a single supporting board and the adjacent memory IC chips are directly connected by means of a bonding wire (6) or the like. Accordingly, this semiconductor memory device allows predetermined semiconductor IC chips to be mounted more densely and more compactly without requiring arrangement of conductive patterns (5) for connecting the semiconductor IC chips on a circuit board.
