Description
Summary:Hamming distance search CAM is a hardware capable of fuzzy search. In the CAM which uses a neuron MOS inverter, the through current flows during search operation and the power consumption increases. In this paper, we propose a new Hamming distance search CAM with clock signals. By using clock signals, the proposed circuit can reduce unnecessary through current flowing during the search operation. We also verify the operation of the proposed CAM by HSPICE simulation and clarify its usefulness.
