resistive random access memory

Thus, an endurance test determines the maximum number of set/reset cycles that can be switched effectively before the HRS and the LRS are no longer distinguishable. Prakash A, Deleruyelle D, Song J, Bocquet M, Hwang H (2015) Resistance controllability and variability improvement in a TaOx-based resistive memory for multilevel storage application. A general schematic illustration depicting the switching process of conductive bridge random access memory cell is shown in Fig. {\frac{r^{2}_{\text{CFmax}}-r^{2}_{\text{CF}}}{r^{2}_{\text{work}}}} $$, $$ I_{\text{cell}} = I_{\mathrm{sub-oxide}} + I_{\text{CF}} + I_{\text{Pristine}} $$, $$ I_{\text{CF}} = F.\pi. A comparative analysis of the RRAM models discussed in this work is presented in Table 5. It is observed that with an increase in (Vreset), the HRS current (IHRS) decreases; thus, multiple HRS levels with the same LRS resistance are obtained. A number of RRAM models with varying features and accuracy have been proposed [129]. A practically viable approach is to map an ANN to a RRAM-based neuromorphic network directly. The Ag top electrode (TE) is an active component in the filament formation while the bottom Pt electrode is inert.

The improvement in the SET voltage and the resistance distribution of the RRAM device after inserting a thin Al buffer layer between TiN electrode and HfO x bulk oxide and the same is depicted in Fig. The cell current distributions show a small variation for initial and final cycles. Depending upon how memory cells are organized, Flash memory is classified as NOR Flash and NAND Flash [1]. Nat Mater 10(8):625–630. For silicon-based electrodes, p-type Si and n-type Si [63] are the only types of electrodes used.

S To describe the drift-diffusion of vacancy migration, this model assumes the same equation can be used to describe both the processes of oxygen ions and vacancies. The aforesaid issues need to be handled effectively before implementing RRAM in future memory applications. Owing to their small physical size and low power consumption, resistive random access memory (RRAM) devices are potential for future memory and logic applications in microelectronics. It is also observed that I reset increases with increasing Icc as higher power is required to rupture the CF having larger diameter. The conventional RRAM (Resistive Random-Access Memory) is just a metal-insulator-metal structure where the metal oxide is utilized as an insulator. RSC Adv 7(21):12984–12989.
