Ultra low-power design techniques for content addressable memory (CAM)

Content addressable memory (CAM) is an important component for high performance search operations, used in many applications such as pattern matching, database engines and networking IP address lookup. However, conventional CAM designs consume a large amount of power, thus preventing the implementat...
