Memristor technology in future electronic system design

The memristor is a new nanoelectronic device very promising for emerging technologies. Although 40 years ago Leon Chua has postulated this circuit element, only the invention of the crossbar latch by the HP group of Stanley Williams provided the first nanoelectronic realization of such a device in 2008. Thus it has been shown that the ideal circuit elements (R,C,L) were not sufficient to model basic real-world circuits. Memristors being essentially resistors with memory are able to perform logic operations as well as storage of information. Recently, it has been announced that "Williams expects to see memristors used in computer memory chips within the next few years. HP Labs already has a production-ready architecture for such a chip" (http://www.hpl.hp.com/news/2010/apr-jun/memristor.html). Memristors are outstanding candidates for future analog, digital, and mixed signal circuits.
