SAN JOSE, Calif. - South Korea's Hynix Semiconductor Inc. said that it has begun mass producing 64-gigabit NAND flash chips using 20-nm class technology at its 300-mm fab, dubbed M11.
The company developed this previously-announced technology last February. Hynix’s 20-nm class 64-Gb chip doubles the density in a package over the current 32-Gb product.
Hynix' device is said to be a 26-nm part, analysts said. Others are also ramping 20-nm class products. Samsung is ramping a 27-nm NAND device, IM Flash is shipping a 25-nm device, and SanDisk/Toshiba have talked about a 24-nm product.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
