Breaking Down The AI Memory Wall
By Steven Woo - 12 Sep, 2019 - Comments: 0

Over the past few decades, the semiconductor industry has witnessed the rapid evolution of memory technology as new memories helped to usher in new usage models that characterized each decade. For example, synchronous memory helped drive the personal computer (PC) revolution in the 1990s, and this was quickly followed by specialized graphics memory (GPUs) for game consoles in the 2000s. When sm... » read more

GDDR Accelerates Artificial Intelligence And Machine Learning
By Frank Ferro - 16 Jul, 2019 - Comments: 0

The origins of modern graphics double data rate (GDDR) memory can be traced back to GDDR3 SDRAM. Designed by ATI Technologies, GDDR3 made its first appearance in NVidia’s GeForce FX 5700 Ultra card which debuted in 2004. Offering reduced latency and high bandwidth for GPUs, GDDR3 was followed by GDDR4, GDDR5, GDDR5X and the latest generation of GDDR memory, GDDR6. GDDR6 SGRAM supports a ma... » read more

The Importance Of Using The Right DDR SDRAM Memory
By Vadhiraj Sankaranarayanan - 14 Mar, 2019 - Comments: 0

Selecting the right memory technology is often the most critical decision for achieving the optimal system performance. Designers continue to add more cores and functionality to their SoCs; however, increasing performance while keeping power consumption low and silicon footprint small remains a vital goal. DDR SDRAMs, DRAMs in short, meet these memory requirements by offering a dense, high-perf... » 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

Making Sense Of DRAM
By Ed Sperling - 13 Dec, 2018 - Comments: 0

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     __________________________________ See more tech talk videos here. » read more

High-Performance Memory Challenges
By Ann Mutschler - 12 Apr, 2018 - Comments: 1

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

How AI Impacts Memory Systems
By Steven Woo - 08 Mar, 2018 - Comments: 0

Throughout the 1980’s and early 1990’s computer systems were bottlenecked by relatively slow CPU performance, thereby limiting what applications could do. Driven by Moore’s Law, transistor counts increased significantly over the years, improving system performance and enabling exciting new computing possibilities. Although computing capabilities have advanced significantly in recen... » read more
