Claim of US Patent No. 11,116,072


1. An apparatus, comprising:a semiconductor chip to be disposed between a transmitting semiconductor chip and a receiving semiconductor chip, the semiconductor chip comprising cross-talk noise cancellation circuitry disposed between a disturber trace and a trace to be protected from cross-talk noise emanating from said disturber trace, said trace to be protected from cross-talk noise emanating from said disturber trace to be coupled to a receiver disposed on the receiving semiconductor chip, wherein, a first signal that is to propagate on said disturber trace is to be received by said semiconductor chip at a first input of said semiconductor chip, and wherein, a second signal that is to propagate on said trace to be protected from cross-talk noise emanating from said disturber trace is to be received by said semiconductor chip at a second input of said semiconductor chip, wherein, at least one of said first and second signals are driven by said transmitting semiconductor chip, wherein said disturber trace and said trace to be protected from cross-talk noise emanating from said disturber trace are components of a memory channel.
