Memory On Logic: The Good And Bad
By Brian Bailey - 11 Apr, 2024 - Comments: 0

The chip industry is progressing rapidly toward 3D-ICs, but a simpler step has been shown to provide gains equivalent to a whole node advancement — extracting distributed memories and placing them on top of logic. Memory on logic significantly reduces the distance between logic and directly associated memory. This can increase performance by 22% and reduce power by 36%, according to one re... » read more

How AI 2.0 Will Shape The Memory Landscape
By Emma-Jane Crozier - 11 Apr, 2024 - Comments: 0

AI is such a big part of our lives that we don’t even think about it as “AI”; it’s simply normal life these days. If you’ve asked your home assistant for the weather, used a search engine, or been recommended something to watch today, then that’s all been AI discretely at work. While these AI-enabled applications represent notable advancements in incorporating intelligence into syst... » read more
