Improving Power & Performance Beyond Scaling


Steven Woo, Rambus fellow and distinguished inventor, discusses architectural changes inside of servers and data centers to allow pooling of resources such as memory. That has a big impact on power efficiency and overall performance, but it also allows data centers to customize their architectures and prioritized resources with much more granularity than they can do today. » read more

Shifting Toward Data-Driven Chip Architectures


An explosion in data is forcing chipmakers to rethink where to process data, which are the best types of processors and memories for different types of data, and how to structure, partition and prioritize the movement of raw and processed data. New chips from systems companies such as Google, Facebook, Alibaba, and IBM all incorporate this approach. So do those developed by vendors like Appl... » read more

Data Center Evolution: DDR5 DIMMs Advance Server Performance


Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will en... » read more

Data Overload In The Data Center


Dealing with increasing volumes of data inside of data centers requires an understanding of architectures, the flow of data between memory and processors, bandwidth, cache coherency and new memory types and interfaces. Gary Ruggles, senior product marketing manager at Synopsys, talks about how these systems are being revamped to improve performance and reduce power. » read more

Five Key Changes Coming With DDR5 DIMMs


On July 14th of last year, JEDEC announced the publication of the DDR5 SDRAM standard. This signaled the nearing industry transition to DDR5 server dual-inline memory modules (DIMM). DDR5 memory brings a number of key enhancements that will bring great performance and power benefits in next generation servers. Scaling Data Rates to 6.4 Gb/s You can never have enough memory bandwidth, and DD... » read more

Week In Review: Design, Low Power


Siemens will acquire Avatar Integrated Systems. The company's place-and-route tools, which will become part of Mentor's Xcelerator portfolio, include a netlist-to-GDS full-function block-level physical implementation tool and a complete top-level prototyping, floor-planning and chip assembly tool. Based in Santa Clara, CA, Avatar was formed in 2017 from the acquired assets of ATopTech. ATopTech... » read more

Essential DDR5 Features Designers Must Know


JEDEC has defined and developed three DDR standards – standard DDR, mobile DDR, and graphic DDR – to help designers meet their memory requirements. DDR5 will support a higher data rate (up to 6400 Mb/s) at a lower I/O Voltage (1.1V) and a higher density (based on 16Gb DRAM dies) than DDR4. DDR5 DRAMs and dual-inline memory modules (DIMMs) are expected to hit the market in 2020. This article... » read more

DDR5: The Next-Generation Technology For High Performance Computing


The rapid growth in real-time data requirements for cloud services, IoT, high-performance servers and workstations, hyperscale data centers and big data has increased pressure on memory suppliers to improve memory density and speed. This pressure has resulted in a need for new memory technology that goes beyond the current DDR4 limit of 16 Gb single die capacity and speed of 3200MT/s. Click ... » read more

DDR PHY Training


Brett Murdock, senior product marketing manager at Synopsys, explains how to train the DRAM physical layer using firmware, why that is so important for flexibility, and what kinds of issues engineers encounter when using this approach. » read more

Enterprise-Class DRAM Reliability


Brett Murdock, product manager for memory interfaces at Synopsys, examines demand for DDR5 and DDR4 in both on-premise and cloud implementations, what features are available for which versions, how they affect performance and power, how ECC is implemented, and how the data moves throughout these systems. » read more
