Making Sense Of DRAM


Graham Allan, senior manager for product marketing at Synopsys, examines the different types of DRAM, from GDDR to HBM, which markets they’re used in, and why there is such disparity between them. https://youtu.be/ynvcPfD2cZU » read more

Cloud Drives Changes In Network Chip Architectures


Cloud data centers have changed the networking topology and how data moves throughout a large data center, prompting significant changes in the architecture of the chips used to route that data and raising a whole new set of design challenges. Cloud computing has emerged as the fast growing segment of the data center market. In fact, it is expected to grow three-fold in the next few years, a... » read more

Using High-Bandwidth Memory


eSilicon’s Tim Horel talks about HBM, what engineers need to know to work with this technology, and how it integrates with ASICs at advanced nodes. https://youtu.be/0Yq2XHGF6UE » read more

Processing In Memory


Adding processing directly into memory is getting a serious look, particularly for applications where the volume of data is so large that moving it back and forth between various memories and processors requires too much energy and time. The idea of inserting processors into memory has cropped up intermittently over the past decade as a possible future direction, but it was dismissed as an e... » read more

Measuring And Analyzing SoC Performance With Verdi Performance Analyzer


SoC performance is a key competitive advantage in the marketplace. The choice and configuration of SoC components—protocol IP and interconnects, is geared towards maximizing overall SoC performance. A case in point is the use of HBM (High Bandwidth Memory) technology and controllers. Currently in its third generation, HBM boasts high-performance while using less power in a substantially small... » read more

Deep Learning Neural Networks Drive Demands On Memory Bandwidth


A deep neural network (DNN) is a system that is designed similar to our current understanding of biological neural networks in the brain. DNNs are finding use in many applications, advancing at a fast pace, pushing the limits of existing silicon, and impacting the design of new computing architectures. Figure 1 shows a very basic form of neural network that has several nodes in each layer that ... » read more

High-Performance Memory Challenges


Designing memories for high-performance applications is becoming far more complex at 7/5nm. There are more factors to consider, more bottlenecks to contend with, and more tradeoffs required to solve them. One of the biggest challenges is the sheer volume of data that needs to be processed for AI, machine learning or deep learning, or even in classic data center server racks. “The design... » read more

Toward High-End Fan-Outs


Foundries and OSATs are working on more advanced fan-outs, including some with vertically stacked die inside the package, filling a middle ground between lower-cost fan-outs and systems in package on one side and 2.5D and 3D-ICs on the other. These new [getkc id="202" kc_name="fan-outs"] have denser interconnects than previous iterations, and in some cases they include multiple routing layer... » read more

The Hunt For A Low-Power PHY


Physics has been on the side of chipmakers throughout most of the lifetime of [getkc id="74" comment="Moore's Law"], but when dealing with the world outside the chip, physics is working against them. Pushing data at ever-faster rates through boards and systems consumes increasing amounts of power, but the power budget for chips has not been increasing. Could chips be constrained by their int... » read more

HBM2: It’s All About The PHY


HBM DRAM is currently used in graphics, high-performance computing (HPC), server, networking and client applications. HBM, says JEDEC HBM Task Group Chairman Barry Wagner, provides a “compelling solution” to reduce the IO power and memory footprint for the most demanding applications. Recent examples of second-generation HBM deployment include NVIDIA’s Quadro GP100 GPU which is paired wit... » read more
