Linear Drive Optics May Reduce Data Latency
By Karen Heyman - 11 Apr, 2024 - Comments: 0

Optical and electrical are starting to cross paths at a much deeper level, particularly with the growing focus on 3D-ICs and AI/ML training in data centers, driving changes both in how chips are designed and how these very different technologies are integrated together. At the root of this shift are the power and performance demands of AI/ML. It can now take several buildings of a data cente... » read more

Integrating Energy Efficiency Considerations Into Your Design From The Beginning
By William Ruby - 11 Apr, 2024 - Comments: 0

Data center networking is responsible for consuming about 1% of the global electricity supply. With the advent and integration of AI into various sectors, the pressure on both hardware and software infrastructures, necessitated by neural networks and extensive language models, is expected to increase significantly. The burgeoning energy consumption by hyperscale data centers emerges as an ur... » read more

Strategies For Detecting Sources Of Silent Data Corruption
By Anne Meixner - 12 Mar, 2024 - Comments: 0

Engineering teams are wrestling with how to identify the root causes of silent data corruption (SDC) in a timely and cost-effective way, but the solutions are turning out to be broader and more complex than simply fixing a single defect. This is particularly vexing for data center reliability, accessibility and serviceability (RAS) engineering teams, because even the best tools and methodolo... » read more

Examining The Impact Of Chip Power Reduction On Data Center Economics
By Noam Brousard - 12 Mar, 2024 - Comments: 1

In the rapidly evolving landscape of data centers, optimizing energy consumption has become a critical focus. In this blog post, we'll delve into the intricacies of power consumption, exploring the economics of three key components: CPUs, GPUs, and AI accelerators, and how the implementation of proteanTecs power reduction solution transforms both power efficiency and computational capabilities... » read more

Yield Tracking In RDL
By Ed Sperling - 07 Feb, 2024 - Comments: 0

Yield is a much bigger issue when it comes to panel-level packages, which may contain up to 24 RDL layers. Just finding the defects is a massive challenge, let alone understanding how they will impact the entire device. Many of these advanced packages are being used in data centers for generative AI, and killer defects caused by bridges and opens can cause serious problems. What happens, for in... » read more

Why There Are Still No Commercial 3D-ICs
By Brian Bailey - 29 Jan, 2024 - Comments: 0

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

Can Data Centers Afford To Turn Up The Heat?
By Mark Seymour - 25 Jan, 2024 - Comments: 0

Typically, when we discuss digital twin software for data centers, we highlight how engineers can use data center software to model complex thermals using physics-based simulation and find effective ways to cool IT equipment. However, there are compelling efficiency and cost-saving reasons for data center operators to actively seek to run their data centers hotter. But how can this be done wit... » read more

Reducing Power In Data Centers
By Ed Sperling - 16 Jan, 2024 - Comments: 0

The rollout of generative AI, coupled with more data in general, is requiring data centers to run servers harder and longer. That, in turn, is generating more heat and accelerating aging, and to ensure these systems continue working over their projected lifetimes, chipmakers are building extra margin into chips. That increases the amount of energy required to run and cool them, and it can short... » read more

The Future Of Memory
By Karen Heyman - 11 Jan, 2024 - Comments: 1

Experts at the Table: Semiconductor Engineering sat down to talk about the impact of off-chip memory on power and heat, and what can be done to optimize performance, with Frank Ferro, group director, product management at Cadence; Steven Woo, fellow and distinguished inventor at Rambus; Jongsin Yun, memory technologist at Siemens EDA; Randy White, memory solutions program manager at Keysight; a... » read more

Very Short Reach SerDes In Data Centers
By Ed Sperling - 13 Dec, 2023 - Comments: 0

Speed is critical inside of data centers, and the distance that signals have to travel can have a big impact on time to results. But there are a number of variables that need to be considered, including what is an acceptable loss, how much power can be dissipated in a server rack, and what are the various connection options being used. Keivan Javadi Khasraghi, staff technical product manager at... » read more
