Energy Efficient Novel Design of Static Random Access Memory Memory Cell in Quantum-dot Cellular Automata Approach

This paper introduces a peculiar approach of designing static random access memory (sram) memory cell in quantum-dot cellular automata (qca) technique. the proposed design consists of one 3-input mg, one 5-input mg in addition to a (2×1) multiplexer block utilizing the loop-based approach. the simulation results reveals the excellence of the proposed design. the proposed sram cell achieves 16% and 15% improvement in terms of total number of cell counts and area. similarly, the proposed design structure realizes the overall power dissipation savings up to 35.3% at maximum energy dissipation of circuit, 38.6% at average energy dissipation of circuit, 36.1% at minimum energy dissipation of circuit, 36.4% at average energy dissipation of circuit and 40.1% at average switching energy dissipation compared to the latest reported designs. the power analysis and structural analysis of the proposed design is compared with its state-of-the-art counterpart designs, using qcapro and qcadesigner 2.0.3 tools. the proposed qca based sram cell design can be taken as a base design in building an ultra-low power information generating systems like microprocessors.
