NEW YORK, February 2 – Hewlett Packard has announced that its researchers have discovered a technology that would replace transistors, the fundamental building blocks of a computer, in the forthcoming years. The discovery would help the reinvention of the computer at a molecular scale.
The computer company’s researchers say that they have discovered devices called "crossbar latches" which provide the signal restoration and inversion required for general computing without the need for transistors. These crossbar latches can be manufactured in very small sizes, with several thousand expected to be fitted across a single width of human hair, thus shrinking the size of computers. Stan Williams, director of Hewlett-Packard’s Quantum Science Research Group said, "We are reinventing the computer at the molecular scale. The crossbar latch provides a key element needed for building a computer using nanometre-sized devices that are relatively inexpensive and easy to build." There is need to study the properties of a circuit composed of crossbar latches and then build such circuits, Williams said. These devices are likely to first complement the transistors and gradually replace them, Hewlett Packard added.
