Journal on Electronics Engineering 2249 – 0760 5 1 1 5 Tunnel Static Random Access Memory (TSRAM), Negative Differential Resistance (NDR), Resonant Tunnel Diode (RTD) This paper presents a brief review on different types of Tunnel Static Random Access Memory that has been proposed for low power applications. Many authors and researchers have worked on tunnel SRAM, RTD/HFET low standby power, SRAM gain, cell and Bistable Body Tunnel SRAM and demonstrated the accomplished improvements in power dissipation and performance compared with previous designs for low-power memory operation. It broadly relates to SRAM cell employing a Tunnel Switched Diode (TSD) that acts as the storage medium and is controlled by a pass transistor.
