The logic circuit is the main component of an integrated circuit chip that dictates the operation and performance of the chip. The logic circuit based on a memristor can improve the integration and operation speed of the existing integrated circuit and reduce the chip size and the number of devices used by a single logic circuit. However, most of the research on logic circuits based on memristors has focused only on simulations, and research on the realization of logic circuits by hardware using actual memristors is limited. In this paper, a memristor based on graphene oxide with stable complementary resistive switching characteristics is fabricated, a logic circuit is built by using this device, and the logic functions of “IMP,” “AND,” and “NOR” are successfully realized. The complementary resistive switching device can alleviate the severe power loss caused by the memory separation of the von Neumann architecture. Moreover, its unique structure enables it to realize material logic independently without the use of multiple memristors and resistors, providing a new scheme for the physical realization of logic circuits. It also opens up a new path for integrated chips to break through von Neumann architecture.

Resistive random access memory (RRAM) is integrated computing and storage, but most devices have problems, such as high power consumption and poor consistency, so it is critical to optimize the performance of the device. In this paper, amylum RRAM is prepared by using the quantization effect of gold nanoparticles (Au NPs), which not only improves the consistency of the threshold voltage distribution of the device but also reduces the power consumption of the device and significantly increases the ON/OFF current ratio of the device. This work not only realized multilevel data storage (4 levels, 2 bits) on the same unit, improving the storage density of starch RRAM, but also simulated the synaptic potentiation and depression behavior, providing a way of thinking for the next generation of artificial intelligence and brain-like neural computing.

“…In [12], an adjustable single-molecule rectifier with a rectification ratio of up to 600 has been reported. In [13] a ternary logic gate was designed which has less power consumption than conventional circuits. In [14], molecular AND, NOR, XOR, YES, and NOT gates were presented as four-terminal devices, which consisted of an organic molecule connected to two gold electrodes located between capacitor plates (gate terminals).…”

Conventional semiconductor components can be used for modeling and simulating molecular structures, so the progress in molecular electronics can be accelerated by creating a link between molecular electronics and semiconductor technology. Little work has been done so far on molecular electronic modeling. The present work attempts to focus on molecular electronic modeling by proposing a typical model and discussing its theory. Moreover, the circuit components used for modeling the molecules are introduced. An asymmetric oligo phenylene ethynylene (OPE) molecular diode and a four-benzene molecular diode are designed using the presented typical model. Furthermore, using LTspice software, the currents are obtained from the model and molecules for both OPE molecular diode and four-benzene molecular diode to confirm their appropriate performance. Then transmission spectrum, potential drop profile, and rectification ratio are obtained and analyzed for the four-benzene molecular diode using Atomistix ToolKit (ATK) software. Finally, various molecular gates and molecular memory logic circuits including NOT, NAND, NOR, SR Flip Flop, and D flip-flop are designed using the four-benzene molecular diode model.
