resistive random access memory

Park SG, Yang MK, Ju H, Seong DJ, Lee JM, Kim E, et al. 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. The Fourier steady-state heat equation describes this effect as [144]: where krepresents the oxide layer thermal conductivity, Jis the current density and Tis the device temperature. For RRAM cells exhibiting unipolar switching mechanism, the diffusion of oxygen ions (O 2−) is activated thermally by Joule heating current and as such the oxygen ions diffuse from the interface or the region around the CF due to the concentration gradient.

IEEE Electron Device Lett 32(6):797–799. This decrease in resistance ratio was attributed to the built-up of oxygen-vacancy-related traps inside the HfO2 metal oxide layer [112, 113]. The report sheds light on the current situation of the market size, share, demand, development patterns, and forecast in the coming years.

IEEE. Also, it must be noted that a relatively higher reset current is required in unipolar switching RRAM to raise the local temperature around CF. A much simpler alternative to increase storage density in RRAM devices is by making use of multilevel cell (MLC) storage technology which enables storing more than one bit per cell without reducing the physical device dimensions.

The RRAM device also exhibits rich electrical, thermal, magnetic, and optical effects, in close correlation with the abundant resistive switching (RS) materials, metal-oxide interface, and multiple RS mechanisms including the A general schematic illustration depicting the switching process of conductive bridge random access memory cell is shown in Fig. The resistive random access memory (RRAM) device has been widely studied due to its excellent memory characteristics and great application potential in different fields. What is the difference between a virtual machine and a container? DRAMs employed in a computer system has high capacity and density, but they are volatile, meaning there is a need to refresh every few milliseconds. In this work, recent progress and a detailed overview of RRAM technology are presented. J Phys D Appl Phys 42(5):055112. Nanoscale 6(11):5698–5702. [59]. The MLC characteristics in a RRAM cell can also be obtained by controlling the reset voltage (Vreset) while (Icc) is maintained constant. For silicon-based electrodes, p-type Si and n-type Si [63] are the only types of electrodes used. In conventional electronic devices, the choice of electrode material is important as they act as transport paths for the carriers. For example, in copper/poly(3-hexylthiophene): [6,6]-phenyl-C61-butyric acid methyl ester/indium-tin oxide (Cu/P3HT: PCBM/ITO) structure, a stable resistive switching behavior was observed; however, it disappeared after the Cu electrode was replaced with Pt electrode [60]. It is observed that with the decrease in operation current, the amplitude of RTN increases, thus highly affecting the HRS level. https://doi.org/10.1186/s11671-020-03299-9, DOI: https://doi.org/10.1186/s11671-020-03299-9.
