Addressable Memory (CAM) is a high performance search engine, which access the
data based on its contents in a single clock cycle but the power and area
overhead will increase. To overcome this drawback we need to reduce the power
consumption of the CAM when we search the data. Most memory devices store and
retrieve data by addressing specific memory location. As a result, this path
often becomes the limiting factor for the systems that rely on fast memory
access. Due to their parallel pattern matching property, CAMs are gaining
increasing importance over Random Access Memory (RAM) in recent years, though
design complexity and power consumption continue to remain the major drawbacks.
The challenge in the design of a CAM cell is to reduce leakage power in its
compare circuitry without sacrificing the speed. This paper describes a novel
high-performance low power design of CAM block.
