Abstract
En 中文
This paper presents a novel single-layer, cost-efficient RAM cell design in quantum-dot cellular automata (QCA) nanotechnology, offering significant improvements in efficiency, scalability, and reliability. QCA, as the best alternative transistor-less nanocomputing paradigm to traditional microelectronic technologies, improves practicality for highly polarized digital memory applications, enabling faster operation with set/reset capability and minimizing latency. While energy dissipation is slightly higher than in multilayer designs, the single-layer structure offers key advantages by avoiding the complexity of multilayer fabrication. The proposed RAM cell demonstrates a 32% improvement in the Figure of Merit (FoM), highlighting its superior efficiency for nanocomputing systems. These advancements lay the foundation for future research on multi-bit QCA memory architectures, with potential refinements in energy efficiency, noise resilience, and large-scale integration. The study contributes to the ongoing development of high-performance nanoscale memory solutions for next-generation computing technologies.
