We provide a brief overview of NASICs, and discuss recent work at all fabric levels. We present advances in device design and optimization including omega gated and junctionless nanowire field effect transistors, methodologies for validation of functionality and parameter variation evaluation, new circuit-level sequencing schemes and performance optimization techniques. We also discuss techniques for defect and parameter variation resilience, ongoing fabrication directions including prototyping and scalable assembly efforts, and directions for the future.

Various Graphene based electronic devices and interconnects have been proposed in the past. In this paper, we explore the possibility of a hybrid fabric between CMOS and Graphene by implementing a novel Graphene Nanoribbon crossbar (xGNR) based volatile Tunneling RAM (GNT RAM) and integrating it with the 3D CMOS stack and layout. Detailed evaluation of GNT RAM circuits proposed show that they have considerable advantages in terms of power, area and write performance over 16nm CMOS SRAM. This work opens up other possibilities including multi-state memory fabrics and even an all-graphene fabric can be envisioned on the long term.
