چکیده

Flexible conductive-bridging random-access-memory (RAM) cells were fabricated with a cross-bar memory cell stacked with a top Ag electrode, conductive polymer (poly(n-vinylcarbazole): PVK), electrolyte (polyethylene oxide: PEO), bottom Pt electrode, and flexible substrate (polyethersulfone: PES), exhibiting the bipolar switching behavior of resistive random access memory (ReRAM). The cell also exhibited bending-fatigue-free nonvolatile memory characteristics: i.e., a set voltage of 1.0 V, a reset voltage of -1.6 V, retention time of >1 × 10(5) s with a memory margin of 9.2 × 10(5), program/erase endurance cycles of >10(2) with a memory margin of 8.4 × 10(5), and bending-fatigue-free cycles of ∼1 × 10(3) with a memory margin (I(on)/I(off)) of 3.3 × 10(5).

Te 5 layer used as solid electrolyte in Conductive - Bridge memory devices fabricated on flexible substrate

This paper shows that the well-know chalcogenide Ge2Sb2Te5 (GST) in its amorphous state may be advantageously used as solid electrolyte material to fabricate Conductive-Bridge Random Access Memory (CBRAM) devices. GST layer was sputtered on preliminary inkjet-printed silver lines acting as active electrode on either silicon or plastic substrates. Whatever the substrate, the resistance switching...

Exploring the atomic structure of copper-doped Gd2O3 for the conductive bridging RAM technology

In this study we model the active layer of a conductive-bridging RAM (CBRAM) at the atomic scale. We concentrate our efforts onto a cubic gadolinium oxide c-Gd2O3 doped with a copper atom coming from an electrode (copper-rich) by a redox mechanism. Using ab initio simulations, the formation enthalpies and the specific electronic states related to neutral and charged Cu interstitials are compute...

The role of the local chemical environment of Ag on the resistive switching mechanism of conductive bridging random access memories.

Conductive bridging random access memories (CBRAMs) are one of the most promising emerging technologies for the next generation of non-volatile memory. However, the lack of understanding of the switching mechanism at the nanoscale level prevents successful transfer to industry. In this paper, Ag/GeSx/W CBRAM devices are analyzed using depth selective X-ray Absorption Spectroscopy before and aft...

Resistive switching characteristics of MnOx-based ReRAM

The resistive switching characteristics of MnOx thin film were investigated for resistive random access memory (ReRAM) applications. The devices in the form of metal–insulator–metal structure exhibited reversible resistive switching behaviour under both sweeping voltages and voltage pulses. Formation and rupture of conductive filaments were proposed to explain the resistive switching. When Al w...

Bipolar Resistive Switching Characteristics of HfO2/TiO2/HfO2 Trilayer-Structure RRAM Devices on Pt and TiN-Coated Substrates Fabricated by Atomic Layer Deposition

The HfO2/TiO2/HfO2 trilayer-structure resistive random access memory (RRAM) devices have been fabricated on Pt- and TiN-coated Si substrates with Pt top electrodes by atomic layer deposition (ALD). The effect of the bottom electrodes of Pt and TiN on the resistive switching properties of trilayer-structure units has been investigated. Both Pt/HfO2/TiO2/HfO2/Pt and Pt/HfO2/TiO2/HfO2/TiN exhibit ...
