SAN FRANCISCO—SanDisk Corp. said Monday (June 4) it is now building its iNAND Extreme NAND flash memory using 19-nm process technology, the most advanced process technology in use today for memory chips. In February, SanDisk provided details of its NAND flash implemented at 19-nm at the International Solid State Circuits Conference here.
SanDisk (Milpitas, Calif.) said Monday its 19-nm process technology is being used to enable large-capacity, high-performance embedded NAND devices that are suited for high-end tablets and smartphones.
SanDisk said its iNAND Extreme will be used on reference designs for the Nvidia Tegra 3 4-Plus-1 quad-core processor as a recommended high-performance storage device for high-end tablet and mobile devices using the latest operating systems.
"SanDisk is a key partner for us in showcasing Tegra 3's capabilities,” said Rene Haas, general manager of notebook products at Nvidia, in a statement. "Just as Tegra delivers great performance and battery life in a wide range of mobile devices, iNAND Extreme provides a high performance memory solution to help create a world-class user experience for tablets and mobile devices."
SanDisk’s 128 GB iNAND Extreme comes in a 12-mm by 16-mm package and conforms to the e.MMC 4.5 specification, SanDisk said. It can achieve up to 45-megabyte per second sequential write and 100 MB/sec read speeds, the firm said. Samples of the latest version of iNAND Extreme will be available to customers this month with general availability this summer, SanDisk said.
45-megabyte per second sequential write and 100 MB/sec read speeds is pretty impressive. Sandisk has done a very impressive job of implementing NAND flash implemented at 19-nm. Who is the closest rival to Sansdisk ?
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.
