Power consumption of a Hamming distance search CAM using neuron MOS transistors

We have proposed a Hamming distance search CAM (content addressable memory) using neuron MOS transistors. The proposed CAM can compare stored data and a search data in parallel, and find stored data with Hamming distance within a certain range. These functions of the CAM are useful for data management and pattern recognition, etc. In this paper, we analyze the power consumption of the proposed CAM in interrogation operation. The proposed CAM can reduce search current to perform the interrogation operation with lower power consumption than conventional NOR-type CAM´s with Hamming distance search functions. Furthermore, the results obtained from these analyses are fully confirmed by HSPICE
