摘要：Content Addressable Memory (CAM) is a special type of hardware storage mostly designed for fastlookup applications. It can perform an associative search operation within one clock cycle. However, the parallel searchscheme costs the CAM memory large power consumption. In this paper, we tend to propose a new CAM architecture,called Master–Slave Match Line (MSML) design, that aims to mix the master–slave architecture and charge refillreduction technique to reduce the CAM power dissipated within the match lines (MLs). Unlike the conventional design,wherever one single ML is employed, our design uses one master-ML (MML) and a number of other slave-MLs(SMLs) to carry out the search operation. By sharing the MML charge with merely the mismatched SML, this MSMLdesign can diminish the MML charge refill swing, such that the Match line power consumption can be reducedefficiently. In addition, we further propose a modified 4T-CAM Cell and replace the basic 9T CAM Cell with themodified 4T CAM Cell and propose an MSML Design to reduce the power and area.
