“…In 2010, researchers at HP Labs realized the implicit state logic based on memristor and proved that this calculation was logically complete. This shows that the data in the memristor based storage structure can be directly processed through state logic calculation, so as to realize the organic integration of operation and storage [13][14][15][16][17]. Among them, the basic function of the read-write circuit based on the memristor is to ensure that the resistance state of the memristor can be changed during the write operation, and the information represented by the current memristor resistance state can be accurately read during the read operation, and the original resistance state of the memristor cannot be changed.…”

In recent years, computation-intensive applications, such as artificial intelligence, video processing and encryption, have been developing rapidly. On the other hand, the problems of “storage wall” and “power consumption wall” for the traditional storage and computing separated architectures limit the computing performance. The computational circuits and memory cells based on nonvolatile memristors are unified and become a competitive solution to this problem. However, there are various problems that prevent memristor-based circuits from entering practical applications, one of which is the memristor state deviation problem caused by continuous reading. In this paper, we study some circuits studied by predecessors on read/write circuit, compare the experimental results, analyze the reason for the resistance state deviation of memristor, and put forward a new parallel structure of memristor based on opposite polarity. The logic “1” and logic “0” are represented by the positive and negative voltage difference of two memristors with opposite polarity, which can effectively alleviate the problem of the resistance state deviation caused by continuous reading. A reading voltage of 2 V is applied to the four circuits at the same time, and continuous reading is carried out until the output voltage becomes stable. The voltage offset of the optimized circuit when reading logic “0” is reduced to 78 mV, which is significantly smaller than that of other circuits. In addition, when reading logic “1”, it has the effect of enhancing the information stored in the memristor.

“…The binary operation of MR is in fact depended on two boundary memristances, by controlling memristance to its upper boundary value ( R off ) or lower boundary value ( R on ). This unique binary characteristic endows MR good application advantages in designing logic circuits 17–37 . MR based logic circuits can be divided into two categories based on the use of different state variables as logical values, namely, the memristance based logic and voltage based logic.…”

“…Memristance based logic circuits adopt memristance of steady state to present logical binary values, which possesses high superiority as used in computation and memory circuit due to the nonvolatile of MR, such as MR material implication, [17][18][19][20][21][22][23][24][25][26] MR-aided logic, 27,28 and MR threshold logic. 26,29,30 Voltage based logic circuits utilize terminal voltage of MR as logical binary values, which possesses better compatibility with electronic circuit since no read circuit of memristance is required, such as MR ratioed logic, 26,[31][32][33][34] CMOS-like MR complementary logic, 35 and Boolean logic. 36,37 It is worth noting that, since nanoscale MRs are still not commercially popularized due to high fabrication cost, MR emulators are now mainly used for discovering the potential applications of MR based circuits.…”

Memristor (MR) has attractive characteristics of nanoscale volume and low‐power dissipation and hence possesses superiorities in designing integrated‐circuits. In this paper, a flux‐controlled binary MR emulator is proposed and discussed by detailing its constitutive mathematical relation between memristance and magnetic flux. MR based logical gates are then constructed and applied to pulse train (PT) controlled Buck converters to improve its output voltage response performance. In order to suppress low‐frequency voltage oscillation of PT controlled Buck converters in continuous conduction mode (CCM), inductor current based PT (IC‐PT) control method using the MR‐based logic gates is newly proposed and analyzed. The sampled simulation and experimental results reveals that the IC‐PT controlled Buck converter by utilizing MR based logic gates can achieve fast transient response and minimized low‐frequency voltage oscillation in CCM mode.

In this paper, a memristor model based on FPGA (field programmable gate array) is proposed, by using which the circuit of AND gate and OR gate composed of memristors is built. Combined with the original NOT gate in FPGA, the NAND gate, NOR gate, XOR gate and the XNOR gate are further realized, and then the adder design is completed. Compared with the traditional gate circuit, this model has distinct advantages in size and non-volatility. At the same time, the establishment of this model will add new research methods and tools for memristor simulation research.
