Resistive Switching Model of OxRAM Devices Based on Intrinsic Electrical Parameters
2019 Latin American Electron Devices Conference (LAEDC), 2019In this work, a model for the resistive switching of ReRAM devices that considers the electrical signal of the measurement element is developed. This model works for bipolar devices that have filamentary-type conduction and it is based on the circuit representation of the conductive filament (CF).

Design methodology for area and energy efficient OxRAM-based non-volatile flip-flop
2017 IEEE International Symposium on Circuits and Systems (ISCAS), 2017With the introduction of the Internet of Things (IoT), power consumption became a major design issue in modern system-on-chips. In advanced technologies, leakage power has become a dominant component, especially during sleep periods. Leakage mainly comes from volatile memory elements, e.g., flip-flops that cannot be power-gated in order to retain their

Evaluation of OxRAM cell variability impact on memory performances through electrical simulations
2011 11th Annual Non-Volatile Memory Technology Symposium Proceeding, 2011An investigation in the impact of Oxide-based Resistive Memory RAM devices (OxRRAM) variability on the memory array performances is proposed. Variability in advanced IC designs has emerged as a roadblock and significant efforts of process and design engineers are required to decrease its impact. This is especially true for OxRRAM memory, combining high

Failure of Weibull distribution to represent switching statistics in OxRAM
Microelectronic Engineering, 2017Considering the reasonable similarity in the physical mechanisms governing oxide breakdown and filamentary resistive switching, the use of the Weibull distribution has been widespread in the RRAM community for describing the stochastics of Forming, SET, RESET and read disturb data sets.
