Power/Performance Bits: Aug. 31


Securing memory Researchers at Columbia University suggest several ways to make computing more secure without imposing a system performance penalty. The efforts focus on memory security, specifically pointers. "Memory safety has been a problem for nearly 40 years and numerous solutions have been proposed. We believe that memory safety continues to be a problem because it does not distribute... » read more

Manufacturing Bits: Aug. 3


World’s thinnest magnet Lawrence Berkeley National Laboratory, the University of California at Berkeley and others have developed what researchers say is the world’s thinnest magnet. The one-atom-thin, two-dimensional (2D) magnet could one day pave the way towards new spin electronics or spintronics memory devices and other technologies in the market. Spintronics uses the orientation of... » read more

Blog Review: Jan. 13


Siemens EDA's Harry Foster tracks trends in IC and ASIC design and finds that increased design size is only one dimension of the growing complexity challenge. Synopsys' Chris Clark and Dennis Kengo Oka predicts how the automotive industry will change in 2021, including new standards for security, increased use of AI and V2X technologies, and a growing focus on software. Cadence's Paul McL... » read more

Power/Performance Bits: Dec. 1


Self-erasing chip Researchers from the University of Michigan developed self-erasing chips that could be used to prevent counterfeiting or detect tampering. The technology is based on a new material that temporarily stores energy, changing the color of the light it emits. It self-erases in a matter of days, or it can be erased on demand. "It's very hard to detect whether a device has been t... » read more

Zeptosecond measurements A group of researchers have set a new world’s record for the shortest timespan measurement. DESY, Fritz-Haber-Institute and Goethe University Frankfurt have measured how long it takes for a photon to cross a hydrogen molecule. The result? About 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second (10-21 seconds). This is said to be the sh... » read more

Challenges For Compute-In-Memory Accelerators


A compute-in-memory (CIM) accelerator does not simply replace conventional logic. It's a lot more complicated than that. Regardless of the memory technology, the accelerator redefines the latency and energy consumption characteristics of the system as a whole. When the accelerator is built from noisy, low-precision computational elements, the situation becomes even more complex. Tzu-Hsian... » read more

Compute-In Memory Accelerators Up-End Network Design Tradeoffs


An explosion in the amount of data, coupled with the negative impact on performance and power for moving that data, is rekindling interest around in-memory processing as an alternative to moving data back and forth between the memory and the processor. Compute-in-memory (CIM) arrays based on either conventional memory elements like DRAM and NAND flash, as well as emerging non-volatile memori... » read more

Making Sense Of PUFs


As security becomes a principal design consideration, physically unclonable functions (PUFs) are seeing renewed interest as new players emerge onto the market. PUFs can play a central role in hardware roots of trust (HRoTs), but the messaging in the market can make it confusing to understand the different types of PUF as well as their pros and cons. PUFs leverage some uncertain aspect of som... » read more

Manufacturing Bits: April 14


Complex microparticles A team of researchers have developed the world’s most complex microparticle. In the lab, researchers have assembled hierarchically organized particles with twisted spikes and polydisperse Au-Cys (gold-cysteine) nanoplatelets or nanosheets. The sheets all twist in the same direction. Cysteine is a proteinogenic amino acid. The structure is said to be more complex ... » read more

Election Security At The Chip Level


Technological advances have changed every facet of our lives, from reading to driving to cooking, but one task remains firmly rooted in 20th-century technology — voting. Electronic voting remains doggedly unavailable to most, and almost always unusable to those who have it. For more than a decade, it seems every election is accompanied by numerous reports of voting machine problems. The mo... » read more
