Patent ID: 7875986

Claim:
A semiconductor device comprising: a semiconductor chip; and a substrate with said semiconductor chip mounted thereon; said semiconductor chip including: a first region comprising data signal pads for data signals and a second region comprising data signal pads for data signals being arranged on a first side and a second side of said semiconductor chip, respectively, among first to fourth sides of said semiconductor chip, said first side and said second side of said semiconductor chip facing to each other; and a region comprising command/address signal pads for command/address signals being arranged on a third side of said semiconductor chip; said data signal pads and command/address signal pads on said semiconductor chip electrically connected to corresponding bond fingers on a chip-mounted surface of said substrate by bonding wires, respectively; and said bond fingers including: a first array of bond fingers and a second array of bond fingers arranged on the chip-mounted surface of said substrate, corresponding to said regions for pads for data signals on said first side and said second side of said semiconductor chip, respectively; a group of bond fingers arranged on the chip-mounted surface of said substrate, corresponding to said region for pads for command/address signals on said third side of said semiconductor chip.
