This is a fast generative model for stochastic memory cells. It helps you determine how real-world devices would perform in large-scale circuits, for example when used as resistive weights in a neuromorphic system.

The model is trained on measurement data and closely replicates

• cross-correlations and history dependence of switching parameters
• cycle-to-cycle and device-to-device distributions
• multi-level resistance states
• resistance non-linearity

It is currently implemented in

• Julia for machine learning and general purpose programming (Synaptogen.jl)
• Verilog-A for circuit-level simulations (Synaptogen.va)
