An exhaustive search of the 6C level crosstalk avoidance codes for TSV array

Through-silicon vias (TSVs) is one of the key enabling technologies of 3-D ICs. However, the crosstalk problem among the adjacent TSVs decreases the performance and deteriorates the signal integrity of TSV bus. This paper proposes an exhaustive search technique of 6C crosstalk avoidance codewords that is applicable for TSV arrays of different sizes to suppress the crosstalk noise below 6C level. The proposed technique has lower system overhead than that of 3D 4-LAT and 6CmFNS methods.
