Publication alert "Evaluation Methods for ReRAM Potentiation on Sub-Nanosecond Timescales"

To develop efficient and scalable artificial intelligence systems, memristive devices are investigated as promising circuit elements for emulating biological synaptic behavior. These devices can store synaptic weights which can be updated by gradual potentiation and depression. Our latest research, published in IEEE Transactions on Electron Materials, explores the potential to perform these updates within ultra-short timescales, even below a nanosecond. It introduces two innovative methods for accurately assessing the current response of memristive devices under pulse trains of ultrashort pulses and delays. Whereas such signals are heavily masked by capacitive current, the methods allow for precisely tracing the weight during potentiation and depression down to 50 ps.
