As nanotechnology is emerging, (1) there is a strong need for well-educated nanoscale systems engineers by industry, and (2) research and education efforts are also called to overcome numerous nanoscale systems issues. This paper is to identify necessary teaching elements for nanotechnology and to propose a way to teach nanotechnology by introducing emerging technologies: Crossbar-based Nano-Architecture and Carbon Nanotube FETS. By investigating read-out scheme of the crossbar memory architectures with students, a set of teaching items have been identified for undergraduate nanotechnology curriculum. The simulation of the student shows that the CNTFET-based crossbar memory achieves improvements in both sensing voltages on/off ratio and noise margin compared to the molecular memory implementation.
