A 400mV 0.59mW low-power CAM-based pattern matching system on 65nm SOTB process

A CAM-based matching system for fast exact pattern matching is implemented on ASIC, using 65nm SOTB process, for very low power consumption. The system has a simple structure, which consists of Content Addressable Memory (CAM), AND, SHIFT, and an FSM, does not employ Central Processor Unit (CPU) as well as complicated algorithms. We take advantage of CAM which has an ability of parallel multi-match mode for designing the system. The system is applied to fast pattern matching with various required search patterns without using any search principles. In this paper, the system operates at 400mV, power consumption 0.59mW using SOTB 65nm process.
