Nothing will change the future of PC hardware quite like the mainstreaming of memristors, a new fourth type of electric circuit component that takes its name from "memory" and "resistor."
For a long time, electrical engineers were using three basic components to create their circuits – inductors, capacitors, and resistors. A fourth component means that circuits can now be exponentially more complex.
Hewlett-Packard is already doing big work in this space. HP Labs Fellow R. Stanley Williams said, "“[The memristor] holds its memory longer. It’s simpler. It’s easier to make — which means it’s cheaper — and it can be switched a lot faster, with less energy.”
