LOW POWER CONCEPT FOR CONTENT ADDRESSABLE MEMORY (CAM) CHIP DESIGN

Dejan Georgiev

A Content Addressable Memory (CAM) is a memory unit that performs single clock cycle content matching instead of addresses. CAM's are vast used in look-up table functions , network routers and cache controllers. Since basic lookups are performed over all the stored memory information there is a high power dissipation. In reality there is always trade-offs between power consumption, area used and the speed. Here is presented an conceptual abstraction for content addressable memory chip at architecture level with reduced power requirements based on combination and modifications of power saving techniques.
