Abstract

In this work, we propose a mixed TFET-MOSFET 8T SRAM cell comprising MOSFET cross-coupled inverters, dedicated TFET read stack and TFET write access transistors. Exploiting both the merits of TFET and MOSFET devices, the proposed SRAM cell provides significant improvement in SRAM stability, V_min and performance. The proposed cell is evaluated and compared with the conventional MOSFET 8T cell and pure TFET 8T cell using mixed-mode TCAD simulations. The results indicate that the proposed mixed TFET-MOSFET cell topology is viable for ultra-low voltage operation. Copyright
