The following arctile was taken from EEtimes. Please follow the link to read the complete arcticle Hewlett-Packard Labs is attempting to catapult the memristor, the fourth passive circuit element after resistors, capacitors and inductors, into the electronics mainstream. Invented in 1971, this "memory resistor" represents a potential revolution in electronic-circuit theory akin to the invention of the transistor -- and perhaps its time has finally come. But as with that earlier device, it will take a killer application to get it off the ground.

Where the hearing aid played that role for the transistor, Hewlett-Packard Labs (Palo Alto, Calif.) hopes resistive random-access memories (RRAMs) will open the floodgates for the memristor. HP Labs is promising prototypes of these ultradense memory cells next year.
