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.

Memristor has been widely explored in digital logic circuits where most of the works are focused on basic gate circuits, such as OR and AND logic gates or full adders while few involve flip-flops. In fact, flip-flops are also basic logic units with memory function for various digital systems. In this paper, we present circuit designs for Delay (D) and Jump-Key (JK) flip-flops based on memristor ratioed logic (MRL). The proposed circuit for D flip-flop only needs five memristors and one NMOS transistor, and circuit for JK flip-flop needs seven memristors and two NMOS transistors. Furthermore, the proposed circuits have been mapped into a hybrid memristor-CMOS crossbar array. Compared with previous approaches, the quantity of MOSFET for each proposed circuit has been greatly reduced. Thus, the proposed designs have achieved simpler structure, smaller area, and lower power consumption benefiting from the memristor's nanoscale size and low power consumption. The circuit verification based on PSpice simulation is also provided.

“…Soon, it was found that the memristors are actually non-volatile resistive-devices that can act as memory elements. Since then, memristors have been extensively explored for logic designing [4][5][6], as also, for the logic-realizations inside the memristive-memories [7,8].…”

“…Following this, different synthesis techniques have been reported in the literature for in-memory logic realization using memristors [10][11][12][13]. It is observable from the existing works [6,8,12] that the circuits implemented using MAGIC-style are more energy-efficient than those realized using the IMPLY-technique. Besides, unlike IMPLY [7], MAGIC-based computations [8] do not need additional hardware (resistors).…”

Memristors are two‐terminal nano‐electronic devices that make it possible to design non‐volatile memory and logic circuits with high integration density. The logic operations of memristor‐based circuits are performed by applying suitable voltages across them. Researchers have been widely experimenting with this device to efficiently implement particular logic functions. However, recently, a synthesis methodology for arbitrary logic functions has been reported, where an input Boolean function is first represented as a Binary Decision Diagram (BDD), followed by the mapping of the BDD‐nodes (netlists of 2‐input NOR and NOT gates) inside a cluster of sliced crossbar‐arrays. The authors propose to map the BDD‐nodes for any input Boolean function to the crossbar‐slices using an improved technique, where each BDD‐node is mapped more efficiently, and the node‐logic is implemented following the Memristor Aided loGIC (MAGIC) design style. Our proposed mapping‐based realization of a BDD‐node has superior performance and energy‐efficiency than the existing IMPLY and MAGIC‐based BDD‐node designs techniques, provided all three node‐designs are implemented inside the similar‐sized crossbars. Comparative‐study of the synthesis results showed that the memristive‐circuits generated using our proposed technique are 26.95% faster, and need 42.32% lesser memristors (on average) than their peers, implemented using the existing approach of slicing crossbar‐architecture.
