Mesh Networking Grows For ICs
By Kevin Fogarty - 04 Apr, 2018 - Comments: 0

Mesh networks were invented to create rich interaction among groups of almost-unrelated peers, but now they are showing up in everything from advanced chip packages to IoT networks. The flexibility of a many-to-many peer-connection model made the mesh approach a favorite for two-dimensional network-on-a-chip topologies, to the point where they began to supplant data-bus connections during th... » read more

World's brightest accelerator Japan’s High Energy Accelerator Research Organization (KEK) is readying what is considered the world’s most luminous or brightest particle accelerator. The system, dubbed the SuperKEKB, combines an electron-positron collider with a new and advanced detector. The storage ring system is designed to explore and measure rare decays of elementary particles, such... » read more

Investigating the human brain for quantum computation potential While much has been made of quantum computing processes using ultracold atoms and ions, superconducting junctions and defects in diamonds, researchers are questioning if this could be performed in human brains. In fact, UC Santa Barbara theoretical physicist Matthew Fisher has been asking this question for years. And now as scient... » read more

Long-lived data storage Scientists from RMIT University and Wuhan Institute of Technology demonstrated a next-generation optical disk with up to 10TB capacity and a six-century lifespan using gold nanoparticles. The technology could radically improve the energy efficiency of data centers according to the researchers, using 1000 times less power than a hard disk center by requiring far less ... » read more

Spark Microsystems: LP On-Chip Radios
By Kevin Fogarty - 02 Apr, 2018 - Comments: 0

Spark Microsystems is taking aim at on-chip radios that continue to be the primary source of battery drain, even in power-conserving designs like Bluetooth Low Energy. "If you wear AirPods, something like 80% of the power is going to power the radio, not the sound. That's not the most efficient approach." according to Frederic Nabki, co-founder of Spark Microsystems, and a former professor o... » read more

How To Choose The Right Memory
By Ann Mutschler - 02 Apr, 2018 - Comments: 0

When it comes to designing memory, there is no such thing as one size fits all. And given the long list of memory types and usage scenarios, system architects must be absolutely clear on the system requirements for their application. A first decision is whether or not to put the memory on the logic die as part of the SoC, or keep it as off-chip memory. "The tradeoff between latency and th... » read more

Switching a Perpendicular Ferromagnetic Layer by Competing Spin Currents
By Technical Paper Link - 31 Mar, 2018 - Comments: 0

ABSTRACT "An ultimate goal of spintronics is to control magnetism via electrical means. One promising way is to utilize a current-induced spin-orbit torque (SOT) originating from the strong spin-orbit coupling in heavy metals and their interfaces to switch a single perpendicularly magnetized ferromagnetic layer at room temperature. However, experimental realization of SOT switching to date req... » read more

The Week In Review: Manufacturing

Chipmakers 3D NAND continues to gain steam, but is the industry headed towards a capacity glut in the overall NAND market? Time will tell. In any case, Toshiba is moving forward with its plans to invest in its Fab 6 facility in Japan. The fab will produce the company’s 96-layer 3D NAND devices. Then, Samsung plans to invest $7 billion to double the production capacity for NAND flash memor... » read more
