Abstract

See full text

Various systems and methods for implementing multi-mode semiconductor devices are discussed herein. For example, a multi-mode semiconductor device is disclosed that includes a device package with a number of package pins. In addition, the device includes a semiconductor die with at least two IO buffers. One of the IO buffers is located a distance from a particular package pin and another of the IO buffers is located a greater distance from the particular package pin. The IO buffer located closest to the package pin includes first bond pad electrically coupled to a circuit implementing a first interface type and a first floating bond pad, and the other IO buffer includes a second bond pad electrically coupled to a circuit implementing a second interface type and a second floating bond pad. In some cases, the first floating bond pad is electrically coupled to the circuit implementing the second interface type via a metal layer wire, and the first floating bond pad is electrically coupled to the particular package pin.
