Down with the transistor

New component could radically transform computer chips

1:47pm, April 30, 2008

After going unchallenged for decades, the transistor’s supremacy could come to an end. Researchers have demonstrated a new type of electronic component that could replace transistors as the building blocks of computer chips, and lead to faster, more powerful and less energy-thirsty computers.

Stanley Williams and his collaborators at HP Labs in Palo Alto, Calif., have created a surprisingly simple new device called a memristor. The device is a piece of an electric circuit with baggage: Its history determines its electrical
