Computer chips

Researchers at MIT have designed a new chip component that can “expand the reach of the Internet of Things into 5G,” reports Margo Anderson for IEEE Spectrum. “The discovery represents a broader push for 5G-based IoT tech—using the telecom standard’s low latency, energy efficiency, and capacity for massive device connectivity,” explains Anderson. “The new research also signals an important step toward applications that include smaller, low-power health monitors, smart cameras, and industrial sensors, for instance.” 

CNBC reporter Kif Leswing spotlights Lisa Su '90, SM '91, PhD '94 and her work as CEO of Advanced Micro Devices (AMD). “On Su’s watch, AMD was the first major company to embrace a technology called ‘chiplets,’” writes Leswing. “Instead of manufacturing one big chip with all the elements needed — the compute cores as well as an input and output block — AMD could make smaller chips and then assemble them together.” 

Researchers at MIT have developed a new chip-based system capable of improving “how terahertz (THz) waves pass through silicon chips,” reports Rupendra Brahambhatt for Interesting Engineering. The researchers “applied a principle called matching, which involves reducing the difference between silicon (dielectric constant is 11) and air (dielectric constant is 1) so that more waves can travel through,” writes Brahambhatt. 

Ars Technica reporter Jacek Krywko spotlights how MIT researchers have developed a new photonic chip that that can “compute the entire deep neural net, including both linear and non-linear operations, using photons.” Visiting scientist Saumil Bandyopadhyay '17, MEng '18, PhD '23 explains that: “We’re focused on a very specific metric here, which is latency. We aim for applications where what matters the most is how fast you can produce a solution. That’s why we are interested in systems where we’re able to do all the computations optically.” 

A more than $40 million investment to add advanced nano-fabrication equipment and capabilities to MIT.nano will significantly expand the center’s nanofabrication capabilities, reports Jon Chesto for The Boston Globe. The new equipment, which will also be available to scientists outside MIT, will allow “startups and students access to wafer-making equipment used by larger companies. These tools will allow its researchers to make prototypes of an array of microelectronic devices.”

Neil Thompson, director of the FutureTech research project at MIT CSAIL and a principal investigator MIT’s Initiative on the Digital Economy, speaks with Politico reporter Mohar Chatterjee about generative AI, the pace of computer progress and the need for the U.S. to invest more in developing the future of computing. “We need to make sure we have good secure factories that can produce cutting-edge semiconductors,” says Thompson. “The CHIPS Act covers that. And people are starting to invest in some of these post-CMOS technologies — but it just needs to be much more. These are incredibly important technologies.”

Popular Science reporter Andrew Paul writes that MIT engineers have developed a new chip for smart phones that blocks unwanted signals, which could “greatly reduce production costs, make devices smaller and more efficient, and potentially even improve battery life.” Graduate student Soroush Araei explains that “our research can make your devices work better with fewer dropped calls or poor connections caused by interference from other devices.”

Researchers from MIT have discovered a hardware vulnerability in Apple’s M1 chip using an attack called PACMAN, reports Harry Guinness for Popular Science. “Attackers can only use PACMAN to exploit an existing memory bug in the system, which can be patched,” explained Guinness.

CSAIL researchers have found a security vulnerability in Apple’s M1 chip, reports Philip Tracy for Gizmodo. “The flaw could theoretically give bad actors a door to gain full access to the core operating system kernel,” explains Tracy.

MIT researchers have discovered a hardware vulnerability in Apple’s M1 chips that can allow attackers to break through its security defenses, reports Carly Page for TechCrunch. “Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory, however, have created a novel hardware attack, which combines memory corruption and speculative execution attacks to sidestep the security feature,” writes Page.

Writing for Forbes, Joseph Coughlin, director of the AgeLab, explores the question of whether microchip tracking technology could potentially become widely accepted. “Such technology forces us to prioritize the value we assign to personal independence and freedom versus the promise of safety and wellbeing,” writes Coughlin.

Rebellions Inc., a company founded by alumnus Park Sunghyun S.M. ’11, PhD ’14, is developing a microchip aimed at “running artificial intelligence more efficiently, which could cut precious millionths of a second off the reaction times of automatic-trading machines,” reports Hooyeon Kim and Whanwoong Choi for Bloomberg. 

Researchers from MIT Lincoln Laboratory have developed a new quantum chip with integrated photonics, a “vital step to advance the evolution of trapped-ion quantum computers and quantum sensors,” reports Paul Smith-Goodson for Forbes.

In an article for Fast Company, Charles Fishman explores how MIT researchers pioneered the use of integrated circuits, technology that is an integral component of today’s digital technologies, in the Apollo 11 computer. “MIT, NASA, and the race to the Moon laid the very foundation of the digital revolution, of the world we all live in,” writes Fishman.

In an article for Forbes, Bill Hardekopf highlights a new hack-proof chip developed by MIT researchers. Hardekopf explains that the chip could help make credit cards more secure.
