Abstract

In the nanoelectronics era with ever smaller devices and higher densities, there are challenges of signal transmission and information communications via interconnects. We examine the interconnect issues for both charge-based and spin-based information systems. For charge-based systems, since there are substantial activities in optical interconnect, this paper focuses on other concepts and approaches. Self-assembled molecular wires, carbon nanotubes/nanowires and virus engineered metallic wires can be used for interconnects. The use of new nano-architectures such as cellular automata, which use mostly nearest neighbors, make the use of self-assembled interconnects even more attractive. These techniques may be applied readily to molecular devices. Spin-based devices offer a new opportunity for low power, high functional throughput applications. We analyze the use of spin waves for information transmission buses referred to as spin wave bus. By introducing these novel circuits built on the spin-based devices and spin wave interconnect, we anticipate enhanced logic functionality. The challenges and issues are discussed.
纳米电子学互连
在纳米电子学时代,器件体积越来越小,密度越来越高,通过互连传输信号和信息通信面临着挑战。我们研究了基于电荷和基于自旋的信息系统的互连问题。对于基于电荷的系统,由于在光互连中有大量的活动,因此本文侧重于其他概念和方法。自组装分子线、碳纳米管/纳米线和病毒工程金属线可用于互连。新的纳米结构的使用,如细胞自动机,主要使用最近邻,使自组装互连的使用更具吸引力。这些技术可以很容易地应用于分子器件。基于自旋的器件为低功耗、高功能吞吐量的应用提供了新的机会。我们分析了自旋波在信息传输总线(称为自旋波总线)中的应用。通过引入这些基于自旋器件和自旋波互连的新型电路,我们期望增强逻辑功能。讨论了挑战和问题。
