    Abstract: The embodiments herein are directed to technologies for crosstalk cancellation structures. One semiconductor package includes conductive metal layers separated by insulating layers, the conductive metal layers for routing signals between external package terminals and pads on an integrated circuit device. Signal lines formed in the conductive metal layers have electrode structure (capacitor electrode-like structures) formed for at least adjacent signaling lines of the package terminals. Two of the electrode structures from the adjacent signaling lines are formed opposite each other on different metal layers.

    Abstract: A memory controller integrated circuit includes a clock signal generator circuit configured to generate a plurality of strobe signals. The memory controller integrated circuit further includes a memory interface circuit coupled to the clock signal generator circuit, the memory interface circuit configured to transmit the plurality of strobe signals to a memory module, wherein each of the plurality of strobe signals is offset with respect to an adjacent strobe signal, and transmit a plurality of data signals to the memory module, wherein a first subset of the plurality of data signals comprises a first nibble and is phase aligned with a first strobe signal of the plurality of strobe signals, and wherein a second subset of the plurality of data signals comprises a second nibble and is phase aligned with a second strobe signal of the plurality of strobe signals.
