Decoder segment optimization of ROM design in quantum dot cellular automata

Emerging technology proves its superiority through quantum dot cellular automata where confinements of electrons occur from all three dimensions. Effective area optimization in quantum dot cellular automata plays a pivotal role in memory designing. In the design of Read Only Memory(ROM), decoding section decides where specific information will be stored. Optimal design of decoder segment signifies the improved memory design. This paper introduces a new design of 4 bit row/column decoder in the ROM design. Designed decoder shows 25.89% reduction of effective area than the latest design proposed by Rigui Zhou et al at the cost of only four majority voter blocks.
