  • Abstract
    In this paper we analyze Random Telegraph Signal (RTS) noise in hafnium-based RRAMs. RTS is measured in HRS, showing fast and slow multilevel switching events. RTS characteristics are examined through novel color-coded time-lag plots and Hidden Markov Model (HMM) time-series analyses. Noise is examined at different reset conditions to provide new insights on conduction mechanisms in HRS. Higher reset voltages result in an enhanced complexity in RTS due to a larger number of active traps.
