Multifunctional Spatially-Expanded Logic Gate for Unconventional Computations with Memristor-Based Oscillators

There is a great variety of unconventional computing approaches trying to compete with and even surpass the classical computers in providing a solution to high complexity problems. Unconventional computation functionality has been verified and implemented successfully on chemical reactions, paving the way to the development of Chemical Computers. This functionality is investigated here, aiming to transfer chemical reaction's working principle on a circuit capable of processing information, involving the interaction of propagating voltage signals in a geometrically constrained electrical medium. In this work such a circuit has been developed utilizing Memristor-Resistor-Capacitor (MemRC) oscillators and their computing capabilities have been verified by demonstrating multiple Boolean logic calculations in the same medium. More specifically, a variety of Boolean gates is implemented in a versatile topology of oscillating nodes, exploiting the same electrical medium geometry.
