Low Leakage and PDP Optimized FinFET based 8T SRAM Design

The paper proposes a Fin Field Effect Transistors (FinFETs) based SRAM design comprising of 8 transistors. The circuit utilizes channel length of 22 nanometers. The operation of this circuit is dependent upon the control switch CS that decides the operating mode and minimizes the leakage current flowing in the cell which in turn lowers the leakage power to a minimal value of 0.331pW. The read buffer available in the design provides a different path for read mode and also enhances the Read Static Noise Margin (RSNM), thus enhancing the readability of the circuit.This design is also able to operate at a minimal voltage of 70mV, thus efficiently utilizing the power available. It also optimizes the power delay product (PDP) for both read and write operations
