Hello can any one please say how to measure min and max resistance for multiple bits for 1T1R

Since you have both voltage and current information, I think you use ohm's law to get that.

@Luke Vassallo at what point need to measure min and max resistance it should measure using BL only or BL and SL?

Use small voltage on BL (0.1 - 0.2 V) and 0 on SL

@Akash Levy min and max resistance means LRS AND HRS ? If so that set and reset means how can I measure both using VBL for HRS voltage will be 0 for reset right then resistance will be 0 And also I wanted to know about the slope measurement how does it work what it is for

min and max resistance means LRS and HRS: yes, basically. LRS and HRS aren’t super well defined, but you can think of it like that you should use a separate pulse to set/reset and a separate pulse to read. so do the RESET pulse, and then do another pulse to read the resistance.

@Akash Levy I am sorry didn't understood for reset that using different pulse by keeping vbl 0 and vsl high so where should I measure HRS or max resistance/reset resistance at what point using vbl or vsl vbl current will go very low when it's vbl is 0 at that point how can I measure? Could you please let me know about slop measurement also please

i’m not understanding your sentence. it is not that complicated. You should typically not try to measure the current during the SET/RESET pulse (e.g., when the VSL is high). This is because the resistance would be changing as you do the measurement… Instead, you should do a separate READ pulse (VBL=0.1-0.2V, VSL=0) afterwards and measure the current during that, then do R=V/I. That way, the resistance isn’t changing while you do the measurement. I think you might need to do more background reading on RRAM, either from Chapter 1+4 of the textbook I sent earlier or from another source.

@Akash Levy thank you so much I will follow your information
