      abstract     = {To understand the switching mechanism in resistive
                      switching memories it is important to study the switching
                      kinetics over several orders in time. One open question is
                      the upper limit of the switching speed. In this study, we
                      present a switching kinetics study on Ta2O5-based resistive
                      memories that spans over 15 order of magnitude in time in a
                      single device. Using coplanar waveguide (CPW) devices
                      switching times less than 35 ps are realized, which are
                      still limited by the measurement setup. In addition, the
                      switching event could be unraveled in the sub-ns regime by
                      analyses of the current transients. The switching kinetics
                      of the CPW devices show the same characteristic as 80 × 80
                      nm2 crossbar devices. Furthermore, we demonstrate multilevel
                      switching with ultrafast sub-ns pulses by variation of the
                      voltage amplitude.},
