Hiding Security Keys Using ReRAM PUFs


Resistive RAM and physically unclonable functions (PUFs) have been gaining traction for completely different reasons, but when combined they create an extremely secure and inexpensive way of storing authentication keys. As security concerns shift from purely software to a combination of hardware and software, chipmakers and systems companies have been scrambling to figure out how to prevent ... » read more

Making PUFs Even More Secure


As security has become a must-have in most systems, hardware roots of trust (HRoTs) have started appearing in many chips. Critical to an HRoT is the ability to authenticate and to create keys – ideally from a reliable source that is unviewable and immutable. “We see hardware roots of trust deployed in two use models — providing a foundation to securely start a system, and enabling a se... » read more

Week In Review: Design, Low Power


Tools Cadence unveiled Cerebrus Intelligent Chip Explorer, a new machine learning-based tool to drive the Cadence RTL-to-signoff implementation flow. The tool aims to use reinforcement learning to find flow solutions that otherwise might not be explored and applies models to future designs. The company says it can improve productivity up to 10X and PPA up to 20% with optimization of the flow f... » read more

Utilizing Computational Memory


For systems to become faster and consume less power, they must stop wasting the power required to move data around and start adding processing near memory. This approach has been proven, and products are entering the marketplace designed to fill a number of roles. Processing near memory, also known as computational memory, has been hiding in the shadows for more than a decade. Ever since the... » read more

Solving The Memory Bottleneck


Chipmakers are scrambling to solve the bottleneck between processor and memory, and they are turning out new designs based on different architectures at a rate no one would have anticipated even several months ago. At issue is how to boost performance in systems, particularly those at the edge, where huge amounts of data need to be processed locally or regionally. The traditional approach ha... » read more

The Next New Memories


Several next-generation memory types are ramping up after years of R&D, but there are still more new memories in the research pipeline. Today, several next-generation memories, such as MRAM, phase-change memory (PCM) and ReRAM, are shipping to one degree or another. Some of the next new memories are extensions of these technologies. Others are based on entirely new technologies or involve ar... » read more

Next-Gen Memory Ramping Up


The next-generation memory market is heating up as vendors ramp a number of new technologies, but there are some challenges in bringing these products into the mainstream. For years, the industry has been working on a variety of memory technologies, including carbon nanotube RAM, FRAM, MRAM, phase-change memory and ReRAM. Some are shipping, while others are in R&D. Each memory type is di... » read more

The Week In Review: Manufacturing


Fab tools and test VLSI Research released its annual "Customer Satisfaction Survey" and listed "THE BEST Suppliers" of 2018. VLSI Research received feedback from more than 94% of the chip market and 76% of subsystems customers for this year’s survey. Who are the winners? Applied Materials reported its second quarter results, along with its business outlook. Compared to the second quarter ... » read more

What Happened To ReRAM?


Resistive RAM (ReRAM), one of a handful of next-generation memories under development, is finally gaining traction after years of setbacks. Fujitsu and Panasonic are jointly ramping up a second-generation ReRAM device. In addition, Crossbar is sampling a 40nm ReRAM technology, which is being made on a foundry basis by China’s SMIC. And not to be outdone, TSMC and UMC recently put ReRAM on ... » read more

The Week In Review: Design


Tools Cadence unveiled a new equivalence checking tool which features a massively parallel architecture capable of scaling to 100s of CPUs and adaptive proof technology that analyzes each partition and determines the optimal formal algorithm. According to the company, the Conformal Smart Logic Equivalence Checker provides an average of 4X runtime improvement with the same resources over the pr... » read more
