ABSTRACT:
Described are systems that employ configurable on-die termination elements that allow users to select from two or more termination topologies. One topology is programmable to support rail-to-rail or half-supply termination. Another topology selectively includes fixed or variable filter elements, thereby allowing the termination characteristics to be tuned for different levels of speed performance and power consumption. Termination voltages and impedances might also be adjusted.
