Design of static random access memory using QCA technology

Quantum dot Cellular Automata(QCA) is one of the emerging trends in the field of nanotechnology which helps to overcome the limitations of CMOS technology. QCA can be used to design memory circuits. Static Random Access Memory (SRAM) is one of the attractive application of QCA technology. The proposed design and simulation of memory cell based on QCA with minimum area and complexity. This paper presents the design and simulation of 16-bit×32-bit SRAM in QCA with minimum number of majority gates and it will be simulated using QCA Designer Tool. SRAM based QCA performance have been compared with CMOS technology using Cadence tool. The comparison results shows that the QCA SRAM circuit provides high efficiency in terms of area, complexity and power consumption.
