Kioxia and Western Digital collectively introduced they’ve developed their sixth-generation, 162-layer 3D flash reminiscence expertise.
This sixth-generation 3D flash reminiscence options superior structure past standard eight-stagger reminiscence gap array and achieves as much as 10% higher lateral cell array density in comparison with the fifth-generation expertise, based on the businesses. This lateral scaling development, together with 162 layers of stacked vertical reminiscence, allows a 40% discount in die dimension in comparison with the 112-layer stacking expertise, optimizing value.
The Kioxia and Western Digital groups additionally utilized Circuit Under Array CMOS placement and four-plane operation, which collectively ship practically 2.four instances enchancment in program efficiency and 10% enchancment in learn latency in comparison with the earlier technology. I/O efficiency additionally improves by 66%, enabling the next-generation interface to assist the ever-increasing want for quicker switch charges.
Overall, the brand new 3D flash reminiscence expertise reduces the price per bit, in addition to will increase the manufactured bits per wafer by 70%, in contrast with the earlier technology.
“Through our strong partnership that has spanned two decades, Kioxia and Western Digital have successfully created unrivaled capabilities in manufacturing and R&D,” mentioned Masaki Momodomi, Kioxia CTO. “Together, we produce over 30% of the world’s flash memory bits and are steadfast in our mission to provide exceptional capacity, performance and reliability at a compelling cost. We each deliver this value proposition across a range of data-centric applications from personal electronics to data centers as well as emerging applications enabled by 5G networks, artificial intelligence and autonomous systems.”
“As Moore’s Law reaches its physical limits across the semiconductor industry, there’s one place where Moore’s Law continues its relevancy – that’s in flash,” mentioned Siva Sivaram, president of expertise and technique for Western Digital. “To proceed these advances and meet the world’s rising knowledge calls for, a brand new strategy to 3D flash reminiscence scaling is crucial. With this new technology, Kioxia and Western Digital are introducing improvements in vertical in addition to lateral scaling to attain higher capability in a…
