Self-aligned Fin Cut Last Patterning Scheme for Fin Arrays of 24nm Pitch and Beyond
By Coventor - 18 Apr, 2019 - Comments: 0

In 5nm FinFET technology and beyond, SRAM cell size reduction to 6 tracks is required with a fin pitch of 24nm. Fin depopulation is mandatory to enable area scaling, but it becomes challenging at small pitches. In the first part of our study, we simulate a FinFET process flow with various fin cut approaches to obtain a 3D model of a FinFET SRAM device. Layout dependent effects on silicon and pr... » read more

More Memory And Processor Tradeoffs
By Ed Sperling - 11 Apr, 2019 - Comments: 0

Creating a new chip architecture is becoming an increasingly complex series of tradeoffs about memories and processing elements, but the benefits are not always obvious when those tradeoffs are being made. This used to be a fairly straightforward exercise when there was one processor, on-chip SRAM and off-chip DRAM. Fast forward to 7/5nm, where chips are being developed for AI, mobile ph... » read more

Target: 50% Reduction In Memory Power
By Brian Bailey - 11 Apr, 2019 - Comments: 3

Memory consumes about 50% or more of the area and about 50% of the power of an SoC, and those percentages are likely to increase. The problem is that static random access memory (SRAM) has not scaled in accordance with Moore's Law, and that will not change. In addition, with many devices not chasing the latest node and with power becoming an increasing concern, the industry must find ways to... » read more

In-Memory Vs. Near-Memory Computing
By Mark LaPedus - 21 Feb, 2019 - Comments: 1

New memory-centric chip technologies are emerging that promise to solve the bandwidth bottleneck issues in today’s systems. The idea behind these technologies is to bring the memory closer to the processing tasks to speed up the system. This concept isn’t new and the previous versions of the technology fell short. Moreover, it’s unclear if the new approaches will live up to their billi... » read more

Pushing AI Into The Mainstream
By Brian Bailey - 31 Jan, 2019 - Comments: 0

Artificial intelligence is emerging as the driving force behind many advancements in technology, even though the industry has merely scratched the surface of what may be possible. But how deeply AI penetrates different market segments and technologies, and how quickly it pushes into the mainstream, depend on a variety of issues that still must be resolved. In addition to a plethora of techni... » read more

Using Memory Differently
By Ann Mutschler - 31 Jan, 2019 - Comments: 0

Chip architects are beginning to rewrite the rules on how to choose, configure and use different types of memory, particularly for chips with AI and some advanced SoCs. Chipmakers now have a number of options and tradeoffs to consider when choosing memories, based on factors such as the application and the characteristics of the memory workload, because different memory types work better tha... » read more

Week in Review: IoT, Security, Auto

Internet of Things Tony Franklin, Intel’s general manager for Internet of Things Segments, is interviewed by Lorin Fries on how the chipmaker is helping to develop smart farming applications. “We focus primarily on high-performance computer technologies, as well as communication technologies, which have great applicability for food systems. We work closely with a broad ecosystem of partner... » read more

Embedded Phase-Change Memory Emerges
By Mark LaPedus - 24 Jan, 2019 - Comments: 3

The next-generation memory market for embedded applications is becoming more crowded as another technology emerges in the arena—embedded phase-change memory. Phase-change memory is not new and has been in the works for decades. But the technology has taken longer to commercialize amid a number of technical and cost challenges. Phase-change memory, a nonvolatile memory type that stores data... » read more

What’s the Right Path For Scaling?
By Mark LaPedus - 02 Jan, 2019 - Comments: 1

The growing challenges of traditional chip scaling at advanced nodes are prompting the industry to take a harder look at different options for future devices. Scaling is still on the list, with the industry laying plans for 5nm and beyond. But less conventional approaches are becoming more viable and gaining traction, as well, including advanced packaging and in-memory computing. Some option... » read more
