abstract = {Memristive cells based on different physical effects, that
is, phase change, valence change, and electrochemical
processes, are discussed with respect to their potential to
overcome the voltage–time dilemma that is crucial for an
application in storage devices. Strongly non-linear
switching kinetics are required, spanning more than 15
orders of magnitude in time. Temperature-driven and
field-driven crystallization, threshold switching, ion
migration, as well as redox reactions at interfaces are
identified as relevant mechanisms. In phase change materials
the combination of a reversible threshold switching and
extremely large crystal growth velocities at high voltages
enables ultra-fast resistive switching whereas lower
voltages will not be sufficient to overcome the energy
barrier for crystallization. In electrochemical cells it
depends on the voltage regime, which mechanism is the
rate-determining one for switching. While
electro-crystallization dominates at low voltages, electron
transfer in the medium voltage range and a mixture of
electron transfer and ion migration at high voltages. In
valence change materials, ion migration is found to be
accelerated by a combined effect of electric field and local
temperature increase due to Joule heating. All discussed
types of resistive switches can provide sufficient
non-linearity of switching kinetics for overcoming the
voltage time dilemma.},
