Thank you @Stefan Schippers what is the threshold voltage of the Reram and is there any document to study more about the Reram

How about https://sky130-fd-pr-reram.readthedocs.io/en/latest/

thank you about that and i am trying to find the threshold voltage for the Reram @Mitch Bailey i am trying to do do some general tests with Reram and just voltage source by changing the input

By threshold voltage, do you mean the SET/RESET voltages? If so, look at https://sky130-fd-pr-reram.readthedocs.io/en/latest/technology_specifications.html#id2
