A new semiconductor integration platform developed at the Institute of Science Tokyo combines advanced chip packaging with high-density interconnects and improved thermal management. This combination of three complementary technologies helps overcome the key challenges in building high-performance artificial intelligence (AI) hardware.... Read more

For the first time, researchers have demonstrated that the "ability to forget" can serve as a new computational function for artificial intelligence.... Read more

The multiplication of matrices and higher-dimensional arrays called tensors lies at the heart of modern computing. Matrix or tensor multiplication is, in fact, the most common operation carried out in artificial intelligence applications, as well as in scientific simulations and computer graphics. High-performance computers, especially those equipped with graphics processing... Read more

Subscriber Identity Modules (SIMs), secure elements used to connect devices to a mobile network, can pose severe security risks when compromised. A malicious SIM could allow attackers to gather information about a device, interfere with its connectivity and serve as an entry point for further cyberattacks.... Read more

AI semiconductors are becoming more programmable. KAIST researchers have developed a device whose response characteristics can be programmed to process data that changes at different speeds. The technology reduced prediction errors for time-varying data by up to 40-fold and is expected to enhance real-time AI performance in autonomous vehicles, robots... Read more

As large language models (LLMs) become increasingly embedded in chatbots, virtual assistants, translation services, coding tools and other AI-powered applications, delivering responses quickly and efficiently has become a growing challenge. Because these models generate text one token at a time, inference can be slow and computationally expensive, particularly for larger... Read more

One of artificial intelligence's most stubborn problems is enabling AI systems to accumulate new knowledge without losing what they previously learned. A team of researchers at the MATRIX AI Consortium at The University of Texas at San Antonio may have solved this issue with Genesis, a spiking neuromorphic accelerator chip... Read more

Mobile phones today handle far more wireless signals and services than earlier generations. The same is true of the sophisticated equipment behind mobile networks, such as base stations, and emerging technologies such as self-driving cars. Inside these systems, radio-frequency switches act like traffic controls, allowing signals to pass or blocking... Read more

A research team has developed the world's first chip that can match the speed at which the human brain functions. The study, titled "A sub–10-millisecond neural dynamical system based on phase-change memristors," was published in Science and was led by Professor Yang Yuchao of Peking University, together with researchers from...

High-frequency waves classified as terahertz occupy a relatively underused region of the electromagnetic spectrum between infrared light and microwaves. Researchers have long recognized their unique potential for applications including ultrafast wireless communication, security screening, remote sensing and medical imaging.... Read more

Infrared cameras can be used to spot useful information that our eyes can't see, such as gases escaping from a pipeline, chemicals in the atmosphere or heat leaking from a building. But sensing infrared light in sophisticated ways still requires expensive, bulky systems.... Read more

Researchers from Tokyo Metropolitan University studying inkjet printing have introduced ultra-fine bubbles into ink droplets and showed that their drying behavior can be tuned without additives. They discovered that the shape of the particle-laden film left after a droplet dries can be radically modified by adjusting the number of bubbles.... Read more

Conventional computers process and store information using separate components, known as a processor and memory unit. Because transferring data from one component to the other can be energy-consuming, many electronics engineers have been trying to develop new devices that rely on a single component to store and process information....

Solving complex optimization problems is central to many modern technologies, from logistics and financial modeling to chip design, communications and artificial intelligence (AI). However, as these problems grow in size, conventional computers often require substantial time and energy to search for good solutions.... Read more

A research team led by Prof. Junghyup Lee of the Department of Electrical Engineering and Computer Science at DGIST has become the first in the world to develop a "time-interleaved noise-shaping SAR ADC (analog-to-digital converter)" semiconductor chip capable of simultaneously measuring multiple biosignals, including electrocardiograms (ECG) and electromyograms (EMG). The... Read more
