Greetings!
Here I have attached a table of condition and set voltages that may be stepped through to perform digital logic operations on a crossbar array. I have checked the results by hand, but have been unable to replicate them in spice (due to a lack of knowledge with ltspice and model creation...) or in real life. Please contact me if you have any applications for my work that are fruitful.
