Ma G, Tang X, Zhang H, Zhong Z, Li J, Su H (2015) Effects of stress on resistive switching property of the NiO RRAM device. As the compliance current (Icc) is increased from 150 μ A to 1 mA, six different LRS are obtained at Icc = 150 μA, Icc = 200 μA, Icc = 300 μA, Icc = 500 μA and Icc = 700 μA, Icc = 1 mA due to the increase in the respective current of LRS (I LRS) while the HRS is maintained constant and the HRS current (I HRS) remains same for all the LRS levels. For OFF state resistance (green rectangles), a weaker temperature dependence was observed in contrast to the ON state resistance (green circles) which exhibited similar characteristics, compared to the cycling case. It must be noted that the forming voltage is found to be dependent on the cell area [73] and oxide thickness [74]. Filament dissolution model is based on rupture of CF under the effect of significant temperature change caused due to Joule heating. Nat Nanotechnol 8(1):13.

Nakayama M (2017) ReRAM technologies: applications and outlook In: 2017 IEEE International Memory Workshop (IMW).. IEEE. RRAM, also known as ReRAM (resistive random access memory), is a form of nonvolatile storage that operates by changing the resistance of a specially formulated solid dielectric material.An RRAM device contains a component called a Memristor -- a contraction of "memory resistor" -- whose resistance varies when different voltages are imposed across it. A volatile memory loses its previous stored data on removing the power supply as is the case for dynamic random-access memory (DRAM) and static random-access memory (SRAM). Increased storage density is among the most critical aspects of memory technology to enable the design of multibit capacity [89] memory cells. a Endurance cycles of HfOx-based RRAM at different SET voltage and cell size b with different thickness (T5= 2 nm, T20= 10 nm) at 2.5 V set voltage. Nat Nanotechnol 10(3):191. The principal advantage of RRAM over other non-volatile technology is high switching speed. Due to the dispersing nature of atomic rearrangements induced in RRAM because of set voltage, the long retention time in LRS is difficult to obtain whereas, in HRS, retention is not a concern as it is usually the natural state of the device and RRAM will continue to remain in this state if no bias (or low bias) is applied. In bipolar switching, on the other hand, the migration of charged species is the main driving force for conductive filament dissolution although Joule heating still contributes to accelerate the migration. This method of obtaining MLC characteristics in RRAM is relatively easier; however, this scheme is energy inefficient. The parameters are defined as [135]: These equations govern the physical transformation of the device during SET and RESET transition, thus essentially controlling the CF growth and rupture. MRAM (magnetoresistive random access memory) is a method of storing data bits using magnetic states instead of the electrical charges used by dynamic random access memory ( DRAM ). Resistive random-access memory (RRAM or ReRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a … To overcome ‘von Neumann bottleneck’, one of the effective ways is brain-inspired neuromorphic computing which has shown promising potential in a wide range of complex and cognitive tasks like visual/audio recognition, self-driving, and real-time big-data analytics. In addition, renewed focus should be towards use of RRAM in embedded memory and non-volatile logic applications as breakthroughs in these fields are much more exciting and significant.

For single device structure, RRAM can share the same bottom electrode whereas, for the crossbar architecture, the separate bottom electrodes are used for each device. The prospective applications of RRAM to various fields such as security, neuromorphic computing, and non-volatile logic systems are addressed briefly. First, a brief overview of the field of emerging memory technologies is provided. A number of RRAM models with varying features and accuracy have been proposed [129]. 6c [103]. With a simple structure of metal oxide placed between electrodes, the manufacturing process is very simple, while still offering such excellent features as low power consumption and fast write. The charge transport mechanism of the conventional ReRAM is because of the metallic filament within the resistive ram. Schematic of the switching mechanism of conductive bridge RRAM.

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. Appl Phys Lett 106(15):153502. In oxygen vacancy-based RRAM (OxRRAM), the physical mechanism that is responsible for resistive switching is generally associated with the generation of oxygen vacancies (V\(_{o}^{2+}\)) and subsequent relocation of oxygen ions (O 2−), thus enabling the formation of conductive filament between the top and bottom electrodes of RRAM cell [59]. In phase change memory, the switching medium consists of a chalcogenide material (commonly Ge2-Sb2-Te5, GST) [5–7]. These memory technologies that depend upon the change of resistance rather than charge to store the information are as follows: (i) phase change memory (PCM), (ii) spin-transfer torque magnetoresistive random access memory (STT-MRAM), and (iii) resistive random access memory (RRAM).

Chiu FC, Shih WC, Feng JJ (2012) Conduction mechanism of resistive switching films in MgO memory devices. This dissimilarity is because the conducting filaments of CBRAM are composed mainly of metal atoms which are relatively easier to drift and diffuse compared to oxygen vacancies, thus causing the degradation of the retention time and endurance characteristics of CBRAM compared to the OxRRAM. The 6 Most Amazing AI Advances in Agriculture. The Pt nano-crystals limit the switching effect into regions with high oxygen vacancy generation probability which results in improved uniformity.
