Abstract
Circuits, methods, and apparatus for multiplexing addresses and data at a memory interface such that multiple data widths are provided without the need to change a motherboard or other printed circuit board design. A specific embodiment of the present invention achieves this using a single integrated circuit design where the datapath width is selected using a bonding option, fuse, data input, or other selection mechanism. The specific embodiment supports both 64 and 128-bit datapaths, though other numbers of datapaths, and other datapath widths are supported by other embodiments.
