ABSTRACTIn this work we explore the mechanisms responsible for Random Telegraph Noise (RTN) fluctuations in HfOx Resistive Random Access Memory (RRAM) devices. The statistical properties of the RTN are analyzed in many operating conditions exploiting the Factorial Hidden Markov Model (FHMM) to decompose the multilevel RTN traces in a superposition of two-level fluctuations. This allows the simultaneous characterization of individual defects contributing to the RTN. Results, together with multi-scale physics-based simulations, allows thoroughly investigating the physical mechanisms which could be responsible for the RTN current fluctuations in the two resistive states of these devices, including also the charge transport features in a comprehensive framework. We consider two possible options, which are the Coulomb blockade effect and the possible existence of metastable states for the defects assisting charge transport. Results indicate that both options may be responsible for RTN current fluctuations in HRS, while RTN in LRS is attributed to the temporary screening effect of the charge trapped at defect sites around the conductive filament.

A new stochastic process was developed by considering the internal performance of macro-states in which the sojourn time in each one is phase-type distributed depending on time. The stationary distribution was calculated through matrix-algorithmic methods and multiple interesting measures were worked out. The number of visits distribution to a determine macro-state were analyzed from the respective differential equations and the Laplace transform. The mean number of visits to a macro-state between any two times was given. The results were implemented computationally and were successfully applied to study random telegraph noise (RTN) in resistive memories. RTN is an important concern in resistive random access memory (RRAM) operation. On one hand, it could limit some of the technological applications of these devices; on the other hand, RTN can be used for the physical characterization. Therefore, an in-depth statistical analysis to model the behavior of these devices is of essential importance.
