Switching variability in polycrystalline compliance-free HfO2-based 1R RRAM is evaluated employing ultra-fast low voltage pulse approach. Changes in filament conductivity are linked to the variations of energy released in a switching process. This study indicates that initial state variability is reduced (suppressed) in more resistive filaments.
