More Data, More Processing, More Chips


Simon Segars, CEO of Arm, sat down with Semiconductor Engineering to talk about the impact of heterogeneous computing and new packaging approaches on IP, the need for more security, and how 5G and the edge will impact compute architectures and the chip industry. SE: There are a whole bunch of new markets opening up. How does Arm plan to tackle those? Segars: Luckily for us, we can design ... » read more

Another Brick Or Two In The Chip Design Wall


Physical challenges come and go in the semiconductor world. But increasingly, they also stick around, showing up in inconvenient places at the worst time. The chip industry has confronted and solved some massive challenges over the years. There was the 1 micron lithography wall, which was supposed to be impenetrable. That was followed by the 193nm litho challenge, which cost many billions of... » read more

Breaking Down The AI Memory Wall


Over the past few decades, the semiconductor industry has witnessed the rapid evolution of memory technology as new memories helped to usher in new usage models that characterized each decade. For example, synchronous memory helped drive the personal computer (PC) revolution in the 1990s, and this was quickly followed by specialized graphics memory (GPUs) for game consoles in the 2000s. When sm... » read more

Blog Review: Aug. 28


Cadence's Paul McLellan takes a look at the numerous challenges in designing and manufacturing Cerebras' massive 400,000 processor, 1.2 trillion transistor chip. Synopsys' Taylor Armerding points to a lack of robust mobile app security and why building in security from the beginning can lead to greater productivity and cost saving. Mentor's Paul Johnston takes a look at what's in store at... » read more

Power/Performance Bits: May 8


Cobalt-free cathodes Researchers at the University of California, Berkeley, built lithium-ion battery cathodes without cobalt that can store 50% more energy than traditional cobalt-containing cathodes. Currently, lithium-ion battery cathodes use layered structures, which cobalt is necessary to maintain. When lithium ions move from the cathode to anode during charging, a lot of space is left... » read more
