Ensuring HBM Reliability


Igor Elkanovich, CTO of GUC, and Evelyn Landman, CTO of proteanTecs, talk with Semiconductor Engineering about difficulties that crop up in advanced packaging, what’s redundant and what is not when using high-bandwidth memory, and how continuous in-circuit monitoring can identify potential problems before they happen. » read more

Reliability Monitoring Of GUC 7nm High-Bandwidth Memory (HBM) Subsystem


This white paper presents the use of proteanTecs’ Proteus for HBM subsystem reliability based on deep data analytics and enhanced visibility, overcoming the limitations of advanced heterogeneous packaging. It will describe the operation concept and provide results from a GUC 7nm HBM Controller ASIC. A typical CoWoS chip has hundreds of thousands of micro-bumps (u-bumps). 3-8 u-bumps are us... » read more

HBM Issues In AI Systems


All systems face limitations, and as one limitation is removed, another is revealed that had remained hidden. It is highly likely that this game of Whac-A-Mole will play out in AI systems that employ high-bandwidth memory (HBM). Most systems are limited by memory bandwidth. Compute systems in general have maintained an increase in memory interface performance that barely matches the gains in... » read more

Improving Reliability Monitoring Of High-Bandwidth Memory


As the quest for increased bandwidth and speed continues, multi-die technologies with advanced memory architectures are introduced. As the complexity of these heterogenous packaging continues to develop, new reliability challenges arise. A new approach to HBM subsystem monitoring and repair provides advanced in-field reliability assurance. By applying analytics to data created by on-chip Age... » read more

Speeding Up 3D Design


2.5D and 3D designs have garnered a lot of attention recently, but when should these solutions be considered and what are the dangers associated with them? Each new packaging option trades off one set of constraints and problems for a different set, and in some cases the gains may not be worth it. For other applications, they have no choice. The tooling in place today makes it possible to de... » read more

Analyzing Testbench Design Performance Using Verdi Performance Analyzer


Performance continues to be key factor for the design of any complex system-on-chip (SoC). Moreover, complexity is increasing every day, which poses a challenge for engineers to track performance of the design, yet they are tasked to continuously increase chip performance. This paper describes the challenge to measure design performance and explains how Verdi Performance Analyzer enables run ti... » read more

Why DRAM Won’t Go Away


Semiconductor Engineering sat down to talk about DRAM's future with Frank Ferro, senior director of product management at Rambus; Marc Greenberg, group director for product marketing at Cadence; Graham Allan, senior product marketing manager for DDR PHYs at Synopsys; and Tien Shiah, senior manager for memory marketing at Samsung Electronics. What follows are excerpts of that conversation. Part ... » read more

3D Power Delivery


Getting power into and around a chip is becoming a lot more difficult due to increasing power density, but 2.5D and 3D integration are pushing those problems to whole new levels. The problems may even be worse with new packaging approaches, such as chiplets, because they constrain how problems can be analyzed and solved. Add to that list issues around new fabrication technologies and an emph... » read more
