“…In [11], the three-valued adder and multiplier are implemented only using memristors, in which the multiplier is implemented using only five memristors, which greatly reduces the number of components used and circuit area, and improves the operational efficiency while reducing the power consumption of the chip. Similar to [11,12] proposed a design scheme of ternary univariate logic and multiplier based on bipolar three-state memristor. The results show that this scheme can effectively reduce circuit interconnection and chip area, and improve the energy efficiency of in-memory computing.…”

In this paper, a high-density programmable logic array based on a ternary memristor crossbar array is designed. Based on the three-valued state characteristics of the ternary memristor, we implement the ternary-OR logic gate and a standard ternary inverter to demonstrate the application of this proposed crossbar by using reconfigurable and programmable connections of the memristor cells in the array. Subsequently, on the basis of these logic gates, ternary NAND gates, NOR gates, XOR gates and XNOR gates are further realized. The above-mentioned logic gates all use memristance as the logic state variable. SPICE simulations are conducted to verify the functionality of the programmable gate array based on the proposed ternary memristor crossbar.

The realization of artificial synapses based on biomaterials is of great significance for the development of environmentally friendly neuromorphic hardware systems and artificial intelligence. In this sense, a bioartificial synapse composited with egg albumen (EA) and multiwalled carbon nanotubes (MWCNTs) is fabricated. Based on the adjustable weight of the artificial synapse, the plasticity of electrical synapses is explored. Due to the photogenerated carriers and thermoelectric effects of carbon nanotubes, the device has optoelectronic properties, so the optoelectronic synaptic plasticity of the device is explored under light pulses. The device is well suited for biological synapses and shows great potential for applications in future high‐density storage and neuromorphic computing systems. In addition, to further study the physical mechanism of the conductive process of the device, the electrical characteristics of the contact interface between carbon nanotubes doped with Fe substitution and the upper electrode Al are mainly analyzed by first principles, and the adsorption, charge distribution, and band structure between them are theoretically studied.

“…A 2-bit ternary adder and multiplier are implemented using VTEAM memristors and Stanford CNTFET transistor models. In the same year, Chen fabricated a memristor device based on nanocolumnar crystalline ZnO thin films and used it to realize a complete set of ternary logic and a ternary multiplier unit [16]. Nevertheless, the logic variables of these circuits are voltage, and the memristors are only used as a computing unit rather than a storage unit.…”

Traditional binary combinational logic circuits are generally obtained by cascading multiple basic logic gate circuits, using more components and complicated wiring. In contrast to the binary logic circuit design in this method, ternary combinational logic circuit implementation is more complicated. In this paper, a ternary circuit design method that does not require cascading basic ternary logic gates is proposed based on a tri-valued memristor, which can directly realize specific logic functions through a series connection of memristors. The ternary encoder, ternary decoder, ternary comparator, and ternary data selector are implemented by this method, and the effectiveness of the circuits is verified by LTspice simulations.
