    摘要: The layout circuit comprises a first 3×2 grid array and a second 3×2 grid array. The first 3×2 grid array comprises first, second and third signal contact points and the first and second fixed potential contact points are coupled to a first fixed potential. The first and second fixed potential contact points are arranged diagonally into the first 2×2 array and the first and second signal contact points are also arranged diagonally into the first 2×2 array. The second 3×2 grid array comprises fourth, fifth and sixth signal contact points and the third and fourth fixed potential contact points are coupled to the first fixed potential. The third and fourth fixed potential contact points are arranged diagonally into the second 2×2 array and the fourth and fifth signal contact points are also arranged diagonally into the second 2×2 array.

    摘要: Memory controllers and methods of optimizing pad sequences thereof are provided. At least two different preferred trace sequences on printed circuit boards for at least one memory device are first provided. One memory controller is then provided to have a core logic circuit, a plurality of input/output (I/O) devices, and a reorderer. The core logic has I/O terminals. Each I/O device on the single chip has a pad. The reorderer is coupled between the core logic circuit and the input/output devices, programmable to selectively connect the input/output devices to the input/output terminals. The reorderer is later programmed to select and connect a portion of the input/output devices to the input/output terminals such that one of the different preferred trace sequences is substantially supported.
