Patent ID: 7170114

Claim:
A semiconductor device comprising: a rectangular shape semiconductor chip, wherein said semiconductor chip includes: first electrodes arranged along longer sides of said semiconductor chip at a peripheral portion of said semiconductor chip; second electrodes arranged along shorter sides of said semiconductor chip at the peripheral portion of said semiconductor chip; first I/O buffers arranged along the longer sides of said semiconductor chip inwardly from said first electrodes; and second I/O buffers arranged along the shorter sides of said semiconductor chip inwardly from said second electrodes; wherein the number of said first I/O buffers is larger than the number of said second I/O buffers, wherein a plurality of said first electrodes are electrically connected to a plurality of said first I/O buffers, and wherein one of said second electrodes is electrically connected to one of said first I/O buffers, and another of said second electrodes is electrically connected to one of said second I/O buffers.
