Data storage: Memory that does it all

  • PDF
TechAndComputer (Aug. 2, 2012) — Using the correct annealing temperature is key to making fast, non-volatile computer memory.

Computers often do not run as fast as they should because they are constantly transferring information between two kinds of memory: a fast, volatile memory connected to the CPU, and a slow, non-volatile memory that remembers data even when switched off. A universal memory that is fast, power-efficient and non-volatile would allow new designs that avoid this bottleneck. Hao...

Chips with self-assembling rectangles: Complex microchip structures in one self-assembling step

  • PDF
TechAndComputer (July 17, 2012) — Researchers at MIT have developed a new approach to creating the complex array of wires and connections on microchips, using a system of self-assembling polymers. The work could eventually lead to a way of making more densely packed components on memory chips and other devices.

The new method -- developed by MIT visiting doctoral student Amir Tavakkoli of the National University of Singapore, along with two other graduate students and three...

Plasmonic chains act like polymers

  • PDF
TechAndComputer (July 12, 2012) — New research at Rice University that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing.

Materials scientists take advantage of strong interactions between chemicals to form polymers that self-assemble into patterns and are the basis of things people use every day. Anything made of plastic is a good example.

Now, Rice...

Plasma startup creates high-energy light to make smaller microchips

  • PDF
TechAndComputer (June 28, 2012) — A University of Washington lab has been working for more than a decade on fusion energy, harnessing the energy-generating mechanism of the sun. But in one of the twists of scientific discovery, on the way the researchers found a potential solution to a looming problem in the electronics industry.

To bring their solution to market two UW engineers have launched a startup, Zplasma, that aims to produce the high-energy light needed to etch the next...

First heralded single photon source made from silicon

  • PDF
TechAndComputer (June 28, 2012) — In an important step towards more practical quantum information processing, researchers from the National Institute of Standards and Technology (NIST), the University of California, San Diego; and the Politecnico di Milano in Milan, Italy, have demonstrated the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies -- interferometers for manipulating the entanglement of...
