  We introduce an approach based on the Chapman-Kolmogorov equation to model
heterogeneous stochastic circuits, namely, the circuits combining binary or
multi-state stochastic memristive devices and continuum reactive components
(capacitors and/or inductors). Such circuits are described in terms of
occupation probabilities of memristive states that are functions of reactive
variables. As an illustrative example, the series circuit of a binary memristor
and capacitor is considered in detail. Some analytical solutions are found. Our
work offers a novel analytical/numerical tool for modeling complex stochastic
networks, which may find a broad range of applications.
