Content Addressable Memory Using XNOR CAM Cell

One of the special types of Computer Memory is said to be as Content Addressable Memory. It is also called as associative array or associative storage, associative memory which can be frequently used in very high speed searching applications such as databases, associative computing, lookup tables and networking. CAM is one type of functional memory which contains huge amount of stored data where the input search data will compare with the stored data and the matching data address will be returned. While comparing to other hardware and software search systems, CAM is faster because it have a single clock cycle throughput. In this paper, we propose an 8-bit XNOR CAM cell to reduce the power efficiency instead of XOR CAM cell. The proposed architecture design is based on a sparse clustered network using BCAM. While searching, this design process will eliminate the parallel comparisons.
