0
China is building a 1 billion yuan (US$145.4 million) superconducting computer. It will be able to help develop new weapons, breaking codes and analyzing intelligence. It will use supercooled circuits made of superconducting materials. It will use 40 to 1000 …

computersQuasi‐Solid‐State Single‐Atom Transistors are 10,000 times smaller than conventional silicon transistors

0
Physicist Professor Thomas Schimmel and his Karlsruhe Institute of Technology (KIT) team have developed a single-atom transistor, the smallest transistor worldwide. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid …

computer memoryDemand for computer memory is surging and DRAM will pass $100 billion this year

0
The DRAM market will grow about 39% this year and surpass $100 billion. It will become the first category of semiconductor to hit that milestone. Samsung is the leading DRAM supplier and Hynix is number two.

chinaChina is testing two prototype candidates for exascale supercomputers

0
China on Sunday put into operation a prototype supercomputer that will test out possible technologies and architectures for an exaFLOP supercomputer in 2020 or 2021. The Sunway exascale computer prototype was developed by the National Research Center of Parallel Computer …

computersMemristor based equation solver could cut energy used by 100 times for longer lasting smartphones

0
Up until now small variations in the current passing through a memristor device was not precise enough for numerical calculations. The Nanoelectronics group, University of Michigan, got around this problem by digitizing the current outputs—defining current ranges as specific bit …

3dDARPA wants to speed up computers by over 1000 times while using less power

0
DARPA has revealed the research teams selected to drive two efforts to go beyond Moore’s law. DARPA’s $1.5 billion Electronics Resurgence Initiative (ERI) wants to jumpstart innovation in the electronics industry. Three Dimensional Monolithic System-on-a-Chip (3DSoC) program has groups from …

computersBreakthrough for topological spintronics memory up to 100 times better in many ways than STT-MRAM

0
Japanese researchers have made the world’s best-performing pure spin current source made of bismuth–antimony (BiSb) alloys, which they report as the best candidate for the first industrial application of topological insulators. This is a big step forward towards spin-orbit torque …
