• HP improves memory through circuit history

  Thirty-seven years ago, Leon Chua, a professor at the University of California at Berkeley, theorised that symmetry demands that there should be a fourth fundamental circuit element, the "memristor" or memory resistor. Now HP thinks its memristor will improve memory and circuit design.

• Scientists carve up tiny transistors to one atom thick

  British scientists have created what they claim is the world's smallest transistor, measuring one atom in thickness and 10 atoms in width.

• IBM explores biological binary for chip refinery

  Can scientists use the binary of biology, DNA, to grow carbon nanotubes into more efficient circuits? IBM thinks so.

• Intel to throttle power by enhancing silicon

  Intel will try to further cut power consumption in its next generation of chips by using improved strained silicon, along with transistors that block power to other circuits, and other added features.

• IBM turns up the transistor heat

  IBM has refined its silicon-germanium chip-manufacturing technology to produce transistors that are far thinner than others.

• Photos: The history of the transistor

  In the 60 years since its invention, the transistor has shrunk from hulking origins to the point where more than six billion can fit in an area the size of a credit card. Follow the history of the transistor from its humble origins in Bell Labs to its possible quantum future.

• Intel unfurls experimental 3D transistors

  Intel plans to unveil more details behind its Tri-Gate transistor, an experimental circuit that could be important in the company's quest to keep up with Moore's Law.

• Double-gate chip stops power leakage

  IBM scientists have made a working RAM chip with two gates for conducting electricity, but problems remain in developing a manufacturing process.

• Intel shrinks chips to 90 nanometres

  The chipmaker says it has produced memory chips in its labs containing 330 million transistors through manufacturing technology that will hit the mainstream next year.

• Chip shoppers: Silicon or plastic?

  A scientist has detailed how to create inexpensive semiconducting plastics that may finally fulfill the promise of reducing the cost of display technology for laptops, mobile phones and other devices.
