In this talk I will present some recent advances on the field of information transmission and storage assisted by noise. Schemes of in-series hysteretic nonlinear elements, modeled by Schmitt triggers, were shown to enable transmission of subthreshold signals, with low probability of errors, for optimal noise intensities. Schemes of closed loops of such elements were also shown to sustain information storage only in the presence of moderate amounts of noise. Fi nally, a discrete circuit capable of generating arbitrary time delays dependent on noise characteristics will be presented. On the other hand, I will show results on the e fect of noise in memristors, where external noise helps to commute resistive states in the presence of a small amplitude driving field. We believe these results are of signi cance since memristors are expected to operate in electronic circuits with a large scale of integration, and as such the ef ects of thermal noise will be significant.
