A Reliable High-speed Compact In-memory Matching Circuit for CAM-Application Based on NV-RAM
This paper presents an effective approach forimplementing content address memory (CAM) based on Nonvolatile random-access memory (NV-RAM) technologies. Weused the 2T-2R bitcell structure implemented on a 65nmCMOS process with a special in-memory matching circuitfor realizing low-delay and energy-efficient lookup operations.The simulation results on Synopsys HSPICE indicate that theproposed CAM design can achieve a search error rate of0.03-4.61%, search energy per bit of 4.36-6.47 fJ, and anextremely small search latency varying from 0.11-0.12 nsdepending on the specific design configurations.
