  • Abstract
    We propose using caching to save power in content-addressable memories (CAMs). By using a small cache along with the CAM, we avoid accessing the larger and higher power CAM. For a cache hit rate of 90%, the cache-CAM (C-CAM) saves 80% power over a conventional CAM, for a cost of 15% increase in silicon area. Even at a low hit rate of 50%, a power savings of 40% is achieved. The proposed C-CAM is employed in the design of a testchip demonstrating a 2.6 fJ/bit/search in a 0.18 mum CMOS process
