Nanowire-Based Programmable Architectures

Dehon, André

Abstract

Chemists can now construct wires which are just a few atoms in diameter; these wires can be selectively field-effect gated, and wire crossings can act as diodes with programmable resistance. These new capabilities present both opportunities and challenges for constructing nanoscale computing systems. The tiny feature sizes offer a path to economically scale down to atomic dimensions. However, the associated bottom-up synthesis techniques only produce highly regular structures and come with high defect rates and minimal control during assembly. To exploit these technologies, we develop nanowire-based architectures which can bridge between lithographic and atomic-scale feature sizes and tolerate defective and stochastic assembly of regular arrays to deliver high density universal computing devices. Using 10nm pitch nanowires, these nanowire-based programmable architectures offer one to two orders of magnitude greater mapped-logic density than defect-free lithographic FPGAs at 22nm.
