Research Bits: June 14


Photonic deep neural network chip Engineers from the University of Pennsylvania built a photonic deep neural network on a 9.3 square millimeter chip they say is faster and more efficient at classifying images, with the ability to process nearly two billion images a second. The chip uses a series of waveguides that form 'neutron layers' mimicking the brain. “Our chip processes information ... » read more

New Ways To Improve Batteries


Researchers around the world are racing to develop more efficient, denser, and safer battery technology, and they are reaching far beyond where research has gone before. Much of this is being driven by concern over exhaust from internal combustion engines, which are responsible for a significant portion of global CO2 emissions. Nearly all carmakers today have announced plans to develop batte... » read more

The Race To Make Better Qubits


One of the big challenges in quantum computing is getting qubits to last long enough to do something useful with them. After decades of research, there now appears to be tangible progress. The challenge with any new semiconductor technology is to improve performance by one or more orders of magnitude without discarding a half-century of progress in other areas. Qubits based on silicon quantu... » read more

Manufacturing Bits: Sept. 28


Self-healing ceramics Texas A&M University has discovered a new self-healing mechanism for ceramics, a technology that could one day be used for jet engines, hypersonic aircraft and nuclear reactors. Ceramics involve various materials that are neither metallic nor organic, but rather they are crystalline and/or glassy, according to the University of Maryland. One common example is clay,... » read more

Database Reconstruction from Noisy Volumes: A Cache Side-Channel Attack on SQLite


Authors: Aria Shahverdi, University of Maryland; Mahammad Shirinov, Bilkent University; Dana Dachman-Soled, University of Maryland Abstract: "We demonstrate the feasibility of database reconstruction under a cache side-channel attack on SQLite. Specifically, we present a Flush+Reload attack on SQLite that obtains approximate (or "noisy") volumes of range queries made to a private database... » read more

Power/Performance Bits: Oct. 12


More stable quantum states Researchers at the University of Chicago found a way to make quantum systems retain coherency 10,000 times longer. The fragile nature of quantum states remains a challenge for developing practical applications of quantum computing, as they can be easily disrupted by background noise coming from vibrations, temperature changes or stray electromagnetic fields. Ap... » read more

Addressing IC Security Threats Before And After They Emerge


Semiconductor Engineering sat down to discuss different approaches to security with Warren Savage, research scientist in the Applied Research Laboratory for Intelligence and Security at the University of Maryland; Neeraj Paliwal, vice president and general manager of Rambus Security; Luis Ancajas, marketing director for IoT security software solutions at Micron; Doug Suerich, product evangelist... » read more

Security Risks In The Supply Chain


Semiconductor Engineering sat down to discuss security in the supply chain with Warren Savage, research scientist in the Applied Research Laboratory for Intelligence and Security at the University of Maryland; Neeraj Paliwal, vice president and general manager of Rambus Security; Luis Ancajas, marketing director for IoT security software solutions at Micron; Doug Suerich, product evangelist at ... » read more

New Security Risks Create Need For Stealthy Chips


Semiconductors are becoming more vulnerable to attacks at each new process node due to thinner materials used to make these devices, as well as advances in equipment used to simulate how those chips behave. Thinner chips are now emitting light, electromagnetic radiation and various other types of noise, which can be observed using infrared and acoustic sensors. In addition, more powerful too... » read more

System Bits: Sept. 11


Everything’s faster in Texas The Frontera supercomputing system was formally unveiled last week at the Texas Advanced Computing Center. The system was deployed in June on the University of Texas at Austin campus. It is the fifth-fastest supercomputer in the world at present and the world's fastest academic supercomputer. Dell EMC and Intel collaborated on fitting out Frontera. Work beg... » read more
