GeTe<sub>9</sub> Ovonic Threshold Switch Memristor-Centered 1S1T1R Cell as Bio-Realistic Stochastic Synapse
Biological synapses conserve significant energy within the brain's complex networks due to their stochastic switching behavior, which is crucial for neuromorphic probabilistic computing. To replicate this, GeTe9 OTS devices were fabricated, exhibiting switching mechanisms consistent with biological synapses, thereby providing the necessary randomness for stochastic synapses. Furthermore, we implemented a bio-realistic stochastic synapse using the proposed “1S1T1R” structure. The random switching characteristics were successfully validated through Cadence simulations.
