Heterogeneous Integration of Graphene and Hafnium Oxide Memristors Using Pulsed-Laser Deposition


A technical paper titled “Heterogeneous Integration of Graphene and HfO2 Memristors” was published by researchers at Forschungszentrum Jülich, Jožef Stefan Institute, and Jülich-Aachen Research Alliance (JARA-FIT). Abstract: "The past decade has seen a growing trend toward utilizing (quasi) van der Waals growth for the heterogeneous integration of various materials for advanced electro... » read more

Overview Of Spin-Orbit Torque Vs. Spin-Transfer Torque For MRAM Devices 


A technical paper titled “Perspectives on field-free spin-orbit torque devices for memory and computing applications” was published by researchers at Northwestern University. Abstract: "The emergence of embedded magnetic random-access memory (MRAM) and its integration in mainstream semiconductor manufacturing technology have created an unprecedented opportunity for engineering computing s... » read more

How To Stop Row Hammer Attacks


Row hammer is a well-publicized target for cyberattacks on DRAM, and there have been attempts to stop these attacks in DDR4 and DDR5, but with mixed results. The problem is that as density increases, distance decreases, making it more likely that flipped bit cell in one row can disturb a bit cell in another, and that bits flipped across an entire row can flip another row. Steven Woo, fellow and... » read more

Research Bits: Jan. 30


Etching tellurite glass Physicists from EPFL and Tokyo Tech propose a way to create photoconductive circuits, where the circuit is directly patterned onto a tellurite glass surface with femtosecond laser light. The exposure formed nanoscale tellurium and tellurium oxide crystals, both semiconducting materials. “Tellurium being semiconducting, based on this finding we wondered if it would ... » read more

Why There Are Still No Commercial 3D-ICs


Building chips in three dimensions is drawing increased attention and investment, but so far there have been no announcements about commercial 3D-IC chips. There are some fundamental problems that must be overcome and new tools that need to be developed. In contrast, the semiconductor industry is becoming fairly comfortable with 2.5D integration, where individual dies are assembled on some k... » read more

Chip Industry Week In Review


By Jesse Allen, Karen Heyman, and Susan Rambo UMC and Intel will collaborate on the development of a 12nm semiconductor process platform to address high-growth markets, such as mobile, communications infrastructure, and networking. Apple reportedly pushed back the launch date of its long-awaited electric vehicle and scaled back the self-driving features to L2 driver assistance, according ... » read more

EDA Back On Investors’ Radar


EDA is transforming from a staid but strategic sector into a hot investment market, fueled by strong earnings and growth, a clamoring for leading-edge and increasingly customized designs across new and existing markets, and the rollout of advanced technologies such as AI for a range of tools that will be needed to develop new architectures with much greater performance per watt. A confluence... » read more

IC Tool Vendors Eye Cloud-Native Future


The promise of scalability and efficiency is accelerating the migration of electronic design automation (EDA) to the cloud. Unlimited on-demand compute resources fundamentally change the chip design paradigm, where tools and workloads are no longer constrained by localized hardware. This is easier said than done, however. Optimizing existing tools and infrastructure, creating a new generatio... » read more

Respect? Confused


In a recent story, I talked about how EDA has gained respect in the financial markets, which is something it has failed to do for decades. EDA, in the eyes of Wall Street, had become a plodder through good times and bad, failing to achieve the growth shown by semiconductor companies or foundries, or the rapid rise to glory of other software companies. Of course, it never experienced the same de... » read more

Five Digital Threads Unify And Simplify Electronic Systems Design And Manufacturing


By Matthew Walsh and Matt Bromley Digital transformation involves the integration of digital technologies and the reimagining of business processes to enhance operations, improve customer experiences, and drive innovation. Digital threads are a key component of this transformation, as they enable the seamless flow of data and information across various stages of a process, system, or organiz... » read more
