The category wise distribution of papers consulted in the preparation of this review manuscript are presented in Fig. In this model, the radius of the CF is the internal state variable which effectively governs the switching rate. The spatial variation in the gap size is accounted for in this model, in addition to the variations which arise due to the stochastic property of the ion process. J Appl Phys 111(9):094104. MRS Online Proceedings Library Archive:1250. Sci Rep 3:1680. Chiu FC, Li PW, Chang WY (2012) Reliability characteristics and conduction mechanisms in resistive switching memory devices using ZnO thin films. The search for decent material systems is the most desirable to obtain superior performances in resistive random access memory (RRAM) devices. #    In addition to the materials engineering approach, a novel programming method has also been suggested to reduce fluctuations. 14. RRAM technology has made significant progress in the past decade as a competitive candidate for the next generation non-volatile memory (NVM). The SET operation corresponds to LRS generally referred to storing logic value ‘1’, whereas the RESET operation correspond to HRS storing logic value ‘0’ in the device. On the other hand, for the higher value of ‘Icc’, the ratio of standard deviation (σ) and average resistance (μ) is low, resulting in a smaller LRS resistance spread. The Resistive Random Access Memory Market report provides a detailed analysis of the dynamic of the market with extensive focus on secondary research. The RRAM further includes a lower electrode formed below the switch region; an upper electrode formed on the memory resistor; and an intermediate electrode formed between the switch region and the memory resistor. This might be quite useful to understand the failure mechanisms of other reliability issues. Discrete solutions are required to implement the model in an electrical simulator. Proc IEEE 105(9):1770–1789. One of the methods utilizes the concept of inserting nano-crystal seeds which confine the paths of the conductive filament by enhancing the effect of local electric field [82, 90, 108]. The resistance switching phenomenon has been observed in a variety of oxides, but binary metal oxides have been extensively studied as a preferred switching material for future non-volatile memory applications primarily due to their compatibility with the CMOS BEOL processing. In this letter, a logic methodology based on 1T1R structure has been proposed to implement functionally complete Boolean logics. A form of non-volatile memory in which a pulse voltage is applied to a metal oxide thin film, creating massive changes in resistance to record ones and zeros. Lee S, Chae S, Chang S, Lee J, Seo S, Kahng B, et al. From these observations, we infer that I-V cycling induces stronger temperature dependence, which decreases the ROFF/RON ratio. The temperature ‘T’ of the device increases to the critical temperature, after which the device is reset and the CF dissolution takes place. Applied Surface Science 2011 , 257 (23) , 9885-9887. (2014) Operation methods of resistive random access memory. Due to this random nature of the CF, the prediction and the precise control of the shape of the CF becomes extremely challenging. SET/RESET process is considered as a result of generation/recombination process of oxygen ions (O2−) and oxygen vacancies (V0). A wide variety of materials have been utilized as electrodes for RRAM.

Lanza M, Wong HSP, Pop E, Ielmini D, Strukov D, Regan BC, et al. This comparison reveals the striking difference in terms of the endurance characteristics of these RRAM memory types. Thus, the resistive switching behavior of this type of RRAM is dominated by the formation and dissolution of the metal filaments. Huang YJ, Shen TH, Lee LH, Wen CY, Lee SC (2016) Low-power resistive random access memory by confining the formation of conducting filaments. A detailed comparison of the various parameters is also presented. HfOx-based RRAM exhibits an excellent endurance performance of 106 cycles on a 1-kb array with 30-nm cell size under 0.18 μm technology and the same is shown in Fig. Appl Phys Lett 113(2):023105. d Accumulation of Ag atoms and Pt electrode leads to growth of highly conductive filament. A resistive random access memory (RRAM) consists of a resistive switching memory cell having a metal-insulator-metal structure generally referred to as MIM structure. In unipolar switching, Joule heating is interpreted as the physical mechanism responsible to rupture a conducting filament during reset operation. Sedghi N, Li H, Brunell I, Dawson K, Potter R, Guo Y, et al. This lecture is a comprehensive tutorial of metal oxide-based RRAM technology from device fabrication to array architecture design. In Ti/HfO x/Pt devices, decrease in R OFF/R ON was observed with temperature-dependent cycling. Straight From the Programming Experts: What Functional Programming Language Is Best to Learn Now?

Chen PY, Yu S (2015) Compact modeling of RRAM devices and its applications in 1T1R and 1S1R array design. DRAM stores the information in the form of charge at the capacitor, and SRAM is based on the storage of charge at the nodes of the cross-coupled inverters, whereas the Flash memory technology uses the floating gate of the transistor to store the charge.

(2013) Physical electro-thermal model of resistive switching in bi-layered resistance-change memory. a test element group (TEG) design for robust signal sensing, is one of the critical challenges for the emergence of RRAM devices. On the application of the positive voltage bias to the Ag top electrode, the oxidation (Ag → Ag + + e −) occurs at the top electrode because of which Ag + cations are generated and get deposited into the dielectric layer (a-ZnO) from the Ag electrode. Microelectron Eng 88(8):2608–2610. Currently, a lot of research is being conducted in the area of RRAM to scale down the dimensions and increase the structural density of memory arrays. Therefore, an increase in the gap between the CF tip and bottom electrode (BE) with increasing reset voltage results in multiple resistance levels of HRS. Russo U, Ielmini D, Cagli C, Lacaita AL, Spiga S, Wiemer C, et al. Although, PUFs based on RRAM have demonstrated remarkable performance; however, still more practical demonstrations and further evaluations are required to work out the maturity of this new primitive within the field of hardware security. Various other methods such as constant voltage forming and hot forming (usually referred to as forming at a higher temperature) have also been investigated to effectively reduce the resistance variations [110]. This model shows strong dependence on temperature; thus, there is a need to account for the change of ‘T’. Although the switching mechanism of both ‘OxRRAM’ and ‘CBRAM’ is discussed in detail, there is still some debate on the switching mechanisms of both the RRAM types [97].
