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 (R-off) to 1.6G Omega and the ON state resistance (R-on) to less than 10 Omega. It can also rapidly cycle through the sense states to study endurance. Solid electrolyte Pt/Ta2O5/Cu memristive switches (R-on/R-off ratio of > 10(4)) are used to highlight this new measurement capability. (C) 2012 The Electrochemical Society.
