Abstract
An integrated circuit includes a first integrated circuit die having a first circuit and a first intra-chip interface and a second integrated circuit die having a second circuit and a second intra-chip interface and a remote interface, wherein the first intra-chip interface and the second intra-chip interface electro-magnetically communicate first signals between the first circuit and the second circuit, and wherein the remote interface is coupled to engage in electromagnetic communications with at least one other integrated circuit. In an embodiment of the present invention, a shielding element shields the electromagnetic communications with the at least one other integrated circuit from the electromagnetic communication of the first signals. In other embodiments, antenna beam patterns or differing polarizations are used to isolate the electromagnetic communications with the remote device from the electromagnetic communication of the first signals.
