Research Bits: Jan. 17


Ionic circuit for neural nets Researchers at Harvard University and DNA Script developed an ionic circuit comprising hundreds of ionic transistors for neural net computing. While ions in water move slower than electrons in semiconductors, the team noted that the diversity of ionic species with different physical and chemical properties could be harnessed for more diverse information process... » read more

Research Bits: Nov. 21


Graphene heater for phase-change switches Researchers from the University of Washington, Stanford University, Charles Stark Draper Laboratory, University of Maryland, and Massachusetts Institute of Technology designed an energy-efficient, silicon-based non-volatile switch that manipulates light through the use of a phase-change material and graphene heater. Aiming to reduce the power consum... » read more

Week In Review: Semiconductor Manufacturing, Test


U.S. President Joe Biden appears ready to increase pressure on Japan and the Netherlands to help block the flow of advanced chip technology to China, where it can be used to develop cutting-edge weapons. "You will see Japan and Netherlands follow our lead," U.S. Commerce Secretary Gina Raimondo told CNBC. Japan plans to budget ¥350 billion ($2.38 billion) in a research collaboration with th... » read more

Post-Quantum And Pre-Quantum Security Issues Grow


General-purpose quantum computers will be able to crack the codes that protect much of the world’s information, and while these machines don’t exist yet, security experts say governments and businesses are starting to prepare for encryption in a post-quantum world. The task is made all the more challenging because no one knows exactly how future quantum machines will work, or even which mat... » read more
