Physical memristor/RRAM/resistive switching device SPICE compact model, that is able to accurately fit both unipolar/bipolar devices settling to its current-voltage relationship.
Main capabilities:
- Accurate modeling of dynamic resistance, mimicking physical device response.
- Modeling switching behavior for bipolar/unipolar devices.
- Cycle and switching event count.
- Modular and extensible: Temperature aware case of study.
- Variability aware: voltage/cycle dependent RTN, cycle to cycle conduction changes.
- Provision of variability dynamics and resistive state retention handling, defining how the device degrades through time/cycle stress.
- Explicit support for multi-level storage, allowing the modeling of Pristine State -the initial High Resistive State (HRS) prior any electroforming-.
