Accurate capture of the Set/Reset characteristics is a necessary but challenging task for the development of memristive switches. Here we describe and demonstrate a technique capable of meeting this challenge. This technique can measure the transient current during the Set/Reset operation with a rise time of 4 ns and simultaneously measure the OFF state resistance (Roff) to 1.6 GΩ and the ON state resistance (Ron) to less than 10 . It can also rapidly cycle through the sense states to study endurance. Solid electrolyte Pt/Ta2O5/Cu memristive switches (Ron/Roff ratio of >104) are used to highlight this new measurement capability.
