Abstract
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.
