Metasurface for optical media Researchers at Purdue University proposed a new way to store information in optical media, such as CDs and DVDs, that could improve both storage capacity and read times. The development focuses on encoding information in the angular position of tiny antennas, allowing them to store more data per unit area. "The storage capacity greatly increases because it is o... » read more

5G switches Researchers from the University of Texas at Austin and University of Lille built a new radio frequency switch that could save power in 5G devices when not actively jumping between different networks and spectrum frequencies. “It has become clear that the existing switches consume significant amounts of power, and that power consumed is useless power,” said Deji Akinwande, a ... » read more

Backscatter Wi-Fi radio Engineers at the University of California San Diego developed an ultra-low power Wi-Fi radio they say could enable portable IoT devices. Using 5,000 times less power than standard Wi-Fi radios, the device consumes 28 microwatts while transmitting data at a rate of 2 megabits per second over a range of up to 21 meters. "You can connect your phone, your smart devices, ... » read more

Scaling Up Compute-In-Memory Accelerators
By Katherine Derbyshire - 19 Mar, 2020 - Comments: 3

Researchers are zeroing in on new architectures to boost performance by limiting the movement of data in a device, but this is proving to be much harder than it appears. The argument for memory-based computation is familiar by now. Many important computational workloads involve repetitive operations on large datasets. Moving data from memory to the processing unit and back — the so-called ... » read more

Hybrid solar for hydrogen and electricity Researchers at the Lawrence Berkeley National Laboratory developed an artificial photosynthesis solar cell capable of both storing the sun's energy as hydrogen through water splitting and outputting electricity directly. The hybrid photoelectrochemical and voltaic (HPEV) cell gets around a limitation of other water splitting devices that shortchange... » read more

Intel vs. GlobalFoundries At the IEEE International Electron Devices Meeting (IEDM) this week, GlobalFoundries and Intel will square off and present papers on their new logic processes. Intel will present more details about its previously-announced 10nm finFET technology, while GlobalFoundries will discuss its 7nm finFET process. As expected, Intel and GlobalFoundries will use 193nm immersi... » read more

5/2 fractional states Using a powerful magnet, Columbia University has observed a quantum particle in a bilayer graphene material, an event referred to as a 5/2 fractional quantum state. The observation could bring the industry closer to quantum computing. More specifically, researchers from Columbia said that they have observed “an anomaly in condensed matter physics—the even-denominat... » read more
