Content Addressable Memory (CAM) Technologies for Big Data and Intelligent Electronics Enabled By Magneto-Electric Ternary CAM

Content addressable memory (CAM) is one of the most promising hardware solutions for high-speed data searching and has many practical applications such as anti-virus scanners, internet protocol (IP) filters, and network switches. Since CAM stores the data in its internal memory elements and compares them with the search data in parallel, it can achieve much faster speed compared to the software lookup.

A Mechanistic Analysis of Oxygen Vacancy Driven Conductive Filament Formation in Resistive Random Access Memory Metal/NiO/Metal Structures

Resistive Random Access Memory (RRAM) devices have drawn much interest in the last decade, particularly the concept of a memristor. In this case, the so-called memristance, which provides the relationship between the change in charge (time integral of the current) and flux (time integral of the voltage), is not a constant as in linear elements, but a function of the charge, resulting in a nonlinear circuit element. Applications of such two-terminal electrical devices that provide high densities and low-power operation include, for instance, neuromorphic-type computing elements.

pH-Dependent Spin State Population and 19F NMR Chemical Shift Via Remote Ligand Protonation in An Iron(II) Complex

The development of transition metal-based molecules and materials that can be switched between low-spin and high-spin electronic states has constituted a highly active area of research over the past several decades. Indeed, the magnetic bistability of such spin-crossover compounds make them potential candidates for molecular switches and chemical sensors, as the spin transition can be controlled by a number of external stimuli, such as temperature, pressure, and light.

Drones Learn Autonomous Flying by Imitating Cars and Bikes

The algorithm DroNet allows drones to fly completely by themselves through the streets of a city and in indoor environments. It produces two outputs for each single input image: a steering angle to keep the drone navigating while avoiding obstacles, and a collision probability to let the drone recognize dangerous situations and promptly react to them.

NASA Alloy Could Fold Wings in Flight

NASA has successfully applied a new technology in flight that allows aircraft to fold their wings to different angles while in the air. Part of the Spanwise Adaptive Wing (SAW) project, the technology could produce multiple in-flight benefits to aircraft in the future, both subsonic and supersonic.

Sandia Computer Modeling Aids Solder Reliability in Nuclear Weapons

Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.

New Research Finds Cause of Alloy Weakness

Sometimes calculations don’t match reality. That’s the problem that has faced materials scientists for years when trying to determine the strength of alloys. There has been a disconnect between the theoretical strength of alloys and how strong they actually are. Why?
