Abstract

A semiconductor device includes a first terminal, a second terminal, and a plurality of third terminals on a substrate. Memory chips are stacked on the substrate in an offset manner. Each memory chip has first pads, second pads, and third pads thereon. A first bonding wire is electrically connected to the first terminal and physically connected to a first pad of each memory chip. A second bonding wire is electrically connected to the second terminal and physically connected to a second pad of each memory chip. A third bonding wire electrically connects one third terminal to a third pad on each memory chip. A fourth bonding wire is connected to the first bonding wire at a first pad on a first memory chip of the stack and another first pad on the first memory chip. The fourth bonding wire straddles over the second bonding wire and the third bonding wire.
