Crossbar latch-based combinational and sequential logic for nano FPGA

Molecular based devices exhibit favorable electrical characteristics that make them candidates for implementing digital electronic circuits at the nanoscale. Previous work focused on using the crossbar array to implement programmable logic arrays in which hybrid CMOS/nano approaches rely on lithographic scale electronics for signal restoration and inversion. In this paper, the crossbar latch, which is an integral part of the crossbar array, is used to implement full combinational logic circuits with signal restoration and inversion. Nano architectures of primary combinational and sequential building blocks are presented since they constitute the basis of a homogeneously structured nanoprocessor or nano FPGA. The presented nano system interacts with lithographic devices only for programming and signal I/O.
