Abstract

Computing systems implemented with nanotechnology will need to employ defect- and fault-tolerant measures to improve their reliability due to the large number of factors that may lead to imperfect device fabrication as well as the increased susceptibility to environmentally induced faults when using nanometer-scale devices. Researchers have approached this problem of reliability from many angles and this survey will discuss many promising examples, ranging from classical fault-tolerant techniques to approaches specific to nanocomputing. The research results summarized here also suggest that many useful, yet strikingly different solutions may exist for tolerating defects and faults within nanocomputing systems. Also included in the survey are a number of software tools useful for quantifying the reliability of nanocomputing systems in the presence of defects and faults
