A novel parallel memory design using 2 Dot 1 electron QCA

In view of the technical limitations of CMOS technology, a serious research initiative is evident towards nanotechnology, as a substitution of the existing technology. Quantum-Dot Cellular Automata constitutes a major field of research in the nanotechnology domain. In this article we are dealing with 2 Dot 1 Electron QCA. This paper proposes a novel parallel memory design both single bit and multi-bit using 2 Dot 1 Electron QCA. The proposed design is going to preserve the stability measure and expected to be optimal.
