2T2M memristor based TCAM cell for low power applications

2T2M memristor based TCAM cell for low power applications This paper presents a 2-transistors-memristors (2T2M) bitcell for content-addressable memory design suitable for low-power applications. It uses memristors to store data and MOS transistors as access devices. The low power proposed design splits the search lines to search logic 1 and logic 0 separately to reduce the search power consumption. Different word sizes of the proposed bitcells with and without low power structure are simulated, including full parasitics using BPTM, 45nm CMOS technology node to evaluate and compare different performance parameters. The proposed low power design reduces the active power dissipation of about 30% compared to the design with conventional search approach.
