  Under normal operations, memristive devices undergo variability in time and
space and have internal dynamics. Interplay of memory and stochastic signal
processing in memristive devices makes them candidates for performing
bio-inspired tasks of information transduction and transformation, where
intrinsic random behavior can be harnessed for high performance of circuits
built up of individual memory storing elements. The paper discusses models of
single memristive devices exhibiting both - dynamic hysteresis and Stochastic
Resonance, addressing also the cooperative effect of correlated noises acting
on the system and occurrence of dirty hysteretic rounding.
