Abstract
One semiconductor device has a wiring substrate, a first semiconductor chip, and a second semiconductor chip. Each semiconductor chip includes a first side and a third side which are opposed, a second side which is perpendicular to the first side, and a fourth side opposing the second side. A first electrode (CA electrode pad) parallel to the first side, and a second electrode (I/O electrode pad) arranged parallel to the second side near the second side, are provided on the first semiconductor chip. A third electrode (CA electrode pad) parallel to the first side, and a fourth electrode (I/O electrode pad) arranged parallel to the fourth side near the fourth side, are provided on the second semiconductor chip.
Claims8
A semiconductor device comprising:
- a wiring board
- a first semiconductor chip mounted on a main surface of the wiring board;
- and
- a second semiconductor chip stacked on a main surface of the first semiconductor chip, wherein the first semiconductor chip and the second semiconductor chip are each formed in the shape of a plate having a planar shape including a pair of mutually-opposing edges, namely a first edge and a third edge, a second edge perpendicular to the first edge, and a fourth edge opposing the second edge,
- wherein the main surface of the first semiconductor chip comprises:
- a plurality of first electrodes aligned in such a way as to form a row parallel to the first edge and passing through a central region of the main surface;
- and
- a plurality of second electrodes aligned in the vicinity of the second edge in such a way as to form a row parallel to the second edge, and
- wherein the main surface of the second semiconductor chip comprises:
- a plurality of third electrodes aligned in such a way as to form a row parallel to the first edge and passing through a central region of the main surface and
- a plurality of fourth electrodes aligned in the vicinity of the fourth edge in such a way as to form a row parallel to the fourth edge.
