Stochastic nanoscale addressing for logic

Abstract

In this paper we explore the area overhead associated with the stochastic assembly of nanoscale logic. In nanoscale architectures, stochastically assembled nanowire decoders have been proposed as a way of addressing many individual nanowires using as few photolithographically produced mesoscale wires as possible. Previous work has bounded the area of stochastically assembled nanowire decoders for controlling nanowire crossbar-based memories. We extend this analysis to nanowire crossbar-based logic and bound the area required to supply inputs to a nanoscale circuit via mesoscale wires. We also relate our analysis to the area required for stochastically assembled signal-restoration layers within nanowire crossbar-based logic.
