Semiconductor device with die-skipping wire bonds

A semiconductor device is disclosed including a wire bonded die stack where the bond wires skip dies in the die stack to provide bond wires having a long length. In one example, the semiconductor dies are stacked on top of each other with offsets along two orthogonal axes so that the dies include odd numbered dies interspersed and staggered with respect to even numbered dies only one of the axes. Wire bonds may be formed between the odd numbered dies, skipping the even numbered dies, and wire bonds may be formed between the even numbered dies, skipping the odd numbered dies. The long length of the bond wires increases an inductance of the wire bonds relative to parasitic capacitance of the semiconductor dies, thereby increasing signal path bandwidth of the semiconductor device.
