The time resolved bipolar resistance switching in a Pt/Cr-doped SrZrO 3/SrRuO3 device has been investigated using pulse voltage. The required switching time between the high and low resistance states (HRS and LRS) is studied as a function of the pulse height and width. The resistance switching is found to be less dependent on the pulse height in the short pulse region. For LRS →HRS and HRS →LRS switching minimum switching times of ∼500 and ∼100 ns are required respectively, at a pulse height above the dc switching voltage. The authors attribute the distinction in the switching time to different switching mechanisms.
