“…The scope of alternatives for the design of memristive logic circuits also includes other notable techniques such as Programmable CMOS/Memristor Threshold Logic [92], CMOS-like Memristor Complementary Logic [93], Parallel Input-Processing Memristor Logic [94] and Memristors-As-Drives Gate Design [95]. In addition, several works employ memristive devices in the development of alternative versions of classic circuits, including full-adders [96,97], Look-Up Tables (LUTs) [98], sense amplifiers [99], majority voters [100], etc.…”

Memristors are a promising building block to the next generation of computing systems. Since 2008, when the physical implementation of a memristor was first postulated, the scientific community has shown a growing interest in this emerging technology. Thus, many other memristive devices have been studied, exploring a large variety of materials and properties. Furthermore, in order to support the design of practical applications, models in different abstract levels have been developed. In fact, a substantial effort has been devoted to the development of memristive based applications, which includes high-density nonvolatile memories, digital and analog circuits, as well as bio-inspired computing. In this context, this paper presents a survey, in hopes of summarizing the highlights of the literature in the last decade.

“…Adders are primarily used as basic units in implementing digital signal processing (DSP) systems for applications like design of analog to digital converters (ADCs) and design of digital filters [8][9][10][11][12][13]. Different techniques are used in the design of a multi bit binary adder, for example ripple carry adder (RCA), carry increment adder (CIA), carry skip adder (CSkA), carry look ahead adder (CLA), carry select adder (CSlA), carry save adder (CSA), and carry bypass adder (CBA) [14][15][16][17][18].…”

Adders are the heart of data path circuits for any processor in digital computer and signal processing systems. Growth in technology keeps supporting efficient design of binary adders for high speed applications. In this paper, a fast and area-efficient modified carry save adder (CSA) is presented. A multiplexer based design of full adder is proposed to implement the structure of the CSA. The proposed design of full adder is employed in designing all stages of traditional CSA. By modifying the design of full adder in CSA, the complexity and area of the design can be reduced, resulting in reduced delay time. The VHDL implementations of CSA adders including (the proposed version, traditional CSA, and modified CSAs presented in literature) are simulated using Quartus II synthesis software tool with the altera FPGA EP2C5T144C6 device (Cyclone II). Simulation results of 64-bit adder designs demonstrate the average improvement of 17.75%, 1.60%, and 8.81% respectively for the worst case time, thermal power dissipation and number of FPGA logic elements.

“…Memristor is a simple metal-insulator-metal sandwich structure, and their resistances can be switched between two digital states, low resistance state and high resistance state [16][17][18], laying the foundation for logical operations. Memristors have demonstrated rich logic and arithmetic functionalities in recent years [8,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Memristor based nonvolatile logic can usually be divided into two classesstateful and non-stateful logic, according to the physical quantities of input and output variables.…”

The physically separated memory and logic units in traditional von Neumann computers place essential limits on the performance and cause increased energy consumption, and hence in-memory computing is required to overcome this bottleneck. Here, a new bipolar memristor based in-memory logic approach is proposed, which is capable of achieving all 16 possible Boolean logic functions in a single device in less than 3 steps. This approach does not require initialization and can facilitate logic cascading, and the calculation taking place in-situ is showcased by 1-bit full adder and 2-bit multiplier with improved efficiency, thus showing a great prospect in future in-memory computing architecture.
