How to run retention and endurance of an analogue memristor?

[Zoliledlamini]

Hi Guys,
I am a first time user of ArcOne. I have been struggling to get the endurance and retention of my device as it behaves in an analogue memristive manner. As such I can't switch it. When I run endurance and retention on one resistive state is read.
Any suggestion?

Hello! This is a question more closely related to your RRAM operation rather than ArC ONE operation. Regardless, you need to first identify what voltages you need to switch the device. If you are already in analogue operation range of your device my recommendation would be to run SwitchSeeker first with a reasonable switching threshold, say 25% at a maximum voltage of 4 V (or more depending on your device). This will produce a plot which is essentially ΔR/R vs voltage. Assuming your device works well you should be able to identify a voltage range where the device starts to exhibit an appreciable change in resistance. You can consider this your SET (or RESET depending on the polarity) voltage of the device and you can use these as the switching voltages in your Endurance test. It's also possible that you need more than 1 pulses to switch the device so I would recommend you experiment with that as well. Be aware that excessive voltage during Endurance will eventually degrade your device to a point that might not be useable.
