Improved Synaptic Characteristics of Oxide-Based Electrochemical Random Access Memory at Elevated Temperatures Using Integrated Micro-Heater
IEEE Transactions on Electron Devices(2022)
Abstract
In this brief, we propose an oxygen-based electrochemical RAM (O-ECRAM) with a micro-heater to enhance the synaptic characteristics. Our findings demonstrate that by accelerating the drift/diffusion of oxygen ions at elevated temperatures, the conductance on/off ratio and weight-update linearity of the O-ECRAM can be improved. To elucidate temperature-dependent synaptic behavior, we fitted weight-update curves using numerical modeling of ion injection from the electrolyte and diffusion within the channel. As a result, the micro-heater-integrated O-ECRAM (WO $_{2.7}$ /HfO $_{1.7}$ ) device exhibits an increased training speed and near-ideal synaptic properties.
