Abstract
A CAM integrated circuit has a stage-implemented CAM cell which operationally separates CAM read operations into distinct stages, including look-up, prioritization and encoding, that execute independently. The staged implementation is achieved by placing registers between operational logic blocks in the CAM cell. The integrated circuit prioritizes inputs received simultaneously on dual input buses to avoid contention.
