content: Dear EEVBees:--Well, it looks as though we finally have a real race on our hands, HP vs Samsung.--HP is at last going into production with their crossbar memristor memory. Hynix will produce ReRam (Resistive RAM) chips within two years. I do not know exactly what they are going to produce, but it would not make much sense, unless an integrated RAM/SSD MacGuffin could be made from the chips. These, with the proper price point, needless to say would sell like hotcakes. See link below for BBC article.http://www.bbc.co.uk/news/technology-11165087--Also see the below for HP's boilerplate press release.http://www.tgdaily.com/hardware-features/51340-hp-and-hynix-tout-reram-as-flash-memory-replacement--Coming up on the outside; The Samsung Advanced Institute of Technology has recently obtained a patent for an "oxygen depletion" switch using Tantalum Dioxide/Pentoxide. They do not call this thing a memristor (probably for patenting reasons), but I think that is what it is. Apparently it shifts holes back and forth in similar way to HP's Titanium Dioxide memristor. I was only able to read an abstract (I could not afford $32 for the entire paper). I would appreciate it if a CE or an EE could opine on this. It would appear that Samsung's switch is ten times larger and one tenth as fast. But maybe it can be scaled down. Samsung seems to be trying a work-around for HP's patents. Although the Koreans are late getting out of the gate, we do seem to have a race on our hands, and that should hot things up nicely. Look for more entries to the field soon.http://www.physorg.com/news/2011-07-korean-creation-faster-resilient-reram.html--See the below link for a listing of HP's recent memristor patents, and a great article on implementation of the memristor cross bar to produce standard microelectronics bits of kit. This article also includes a discussion of AI and Neural Networks. Most of this article is too deep for me, but you Sho' Nuff' Electrical Engineers will probably enjoy it. He does not discuss "Implication Logic" (which memristors will use) vs "Boolean Logic" (set theory), which we use now. If someone knows of a good article on Implication Logic, please post it.http://knol.google.com/k/programmable-crossbar-mem-resistors#--Comments by knowledgeable individuals are humbly solicited. Please help us to understand this coming technology. Also please post any links you think would be helpful to our understanding.--Happy 200th DJ.

content: QuoteWhat exactly do you want to know about it? TheWiki entryon memristors seems half decent, and has plenty for direct references and citations of papers on the subject.That said, I find the device fascinating. Apparently memristors could be used to model artificial neural networks to some degree and related fuzzy logic systems.

content: Dear EEVBees:--There you have it. APBOY wants to know what I want to know. My answer; anything that might be pertinent. Not withstanding remarks by AntiProtonBoy, there my be something one of you who work in the field could add, that many of us would find interesting. The problem I have with not knowing everything, is that I do not know the complete extent of my ignorance."Three weeks in the lab will save you a day in the library every time" Stanley Williams, HP LabsBest RegardsClear Ether
