abstract = {For any application of redox-based resistive switching
devices understanding of variability is of major interest.
In this work, we analyze the dependence of the SET switching
time in pulse measurements of TiN/HfOx/Pt devices on the
initial state before switching. The distribution of the
measured SET times covers up to seven decades in one cell. A
stochastic as well as a deterministic variability component
are identified by relating the initial HRS resistance –
obtained from a READ pulse and from the SET pulse for
comparison – to the SET time. The different resulting
correlations to the SET time for the two descriptions of the
initial resistance are analyzed and linked to the polarity
and voltage dependence of the HRS. In addition, the origin
of the resistance variation is discussed.},
