Probabilistic insight to possibility of new metal filament nucleation during repeated cycling of conducting bridge memory
MIS transistor structure is used to study filament nucleation in CBRAM devices. Electrical evidence of multiple location for filament nucleation is presented. Probabilistic model proposed to evaluate the chance of new filament nucleation. Curvature of ruptured filament has a large impact on new filament likelihood. Multiple filaments can further worsen variability issues in CBRAM devices.
