Power Considerations in Banked CAMs : A Leakage Reduction Approach

Abstract EN

The content-based access of CAMs makes them of great interest in lookup-based operations.

However, the large amounts of parallel comparisons required cause an expensive cost in power dissipation.

In this work, we present a novel banked precomputation-based architecture for low-power and storage-demanding applications where the reduction of both dynamic and leakage power consumption is addressed.

Experimental results show that the proposed banked architecture reduces up to an 89% of dynamic power consumption during the search process while the leakage power consumption is also minimized up to a 91%.
