Lorentzian Switching Dynamics in HZO-Based FeMEMS Synapses for Neuromorphic Weight Storage

, realizing single-device analogue multiplication during readout. The switching-threshold distribution follows a Lorentzian form, and the median threshold obeys a Merz-type field-time law. Using this framework, we demonstrate ∼200 electromechanical weight levels. We further show representative retention and endurance, establishing a compact FeMEMS synaptic weight element for calibration-aware electromechanical multiplication in neuromorphic hardware.
