Implication logic gates that are based on volatile memristors are demonstrated experimentally with the use of relay-based volatile memristor emulators of an original design. The fabricated logic circuit involves two volatile memristors and it is capable of performing four fundamental logic functions (two types of material implication and the negations thereof). Moreover, current-voltage characteristics of individual emulators are recorded and self-sustained oscillations in a resistor-volatile memristor circuit are found. The developed emulator offers a great potential for memristive circuit experiments because of its simplicity, similarity of response with volatile memristors, and low cost. Our findings, which are based on emulators, can easily be reproduced with physical volatile memristors and, thus, open up possibilities for emerging in-memory computing architectures.
