A guess: this uses memristors(i.e. rram). crossbar is a startup in the field, their site gives plenty of details about the tech. http://www.crossbar-inc.com/

- simpsond 11y agoDo memristors read or write based on the applied voltage? I noticed that in some of the intel marketing material.
- p1esk 11y agoHow else would you do read/write?
- simpsond 11y agoI'm not familiar with the physics of memristors or storage in general. I was wondering if a single line is used to read and write, increasing the voltage on write to change the state.
- kragen 11y agoApparently a few different things have been called "memristors", but at least some of them have a resistance that depends upon the integral of current through them into the infinite past. DC current one way to write a 1, the other way to write a 0, and AC current to nondestructively read, I guess. Typically this works through ion migration in the material, and I suspect that resulted in abysmal endurance, putting an end to the promise of memristors.
- kken 11y agoRRAM was there first, and it will previal. Lets just forget about this "memristor" PR-nonesense. HP did as well. (Their activities seem to be dead)
- faragon 11y agoI think this is not the memristor thing. I remember memristor-related posts in Slashdot (2008 [1], 2012 [2]), but the ones related to Intel + Micron (2014 [3], 2015 [4]) tell about "3D nand", which may be just NAND-flash using multiple layers with 3D interconnect. However, the speed and density claims make doubt if in reality this is or not the same as the memristor.

- russdill 11y agoNo, this is not memristors (unless you consider PCM to be a memristor) and it has no relation to crossbar-inc.com. This is phase change memory. https://www.google.com/search?q=site%3Amicron.com+%22cross-point%22+memory https://www.google.com/search?q=site%3Amicron.com+%22cross-p...
- throw1111 11y agoNo, apparently it's not PCM. >While they did not specifically state it, it looks to be phase change memory (edit at the Q&A Intel stated this is not Phase Change).
