NAND flash pioneer Toshiba debuted its 19-nm NAND flash last year and swung into volume production over the summer. The chips feature a two-bit-per-cell architecture for a total of 64 Gb of capacity in a 94 mm2 device and can deliver write speeds as high as 25 MB/s. Toshiba recently announced a family of embedded NAND flash memory modules aimed at smartphones, video cameras, and tablets. Densities range from 4 GB to 128 GB. The company also has three-bit-per-cell chips under development.
Thanks for the story...this is a good list of what each memory vendor has been doing and are up to. A good summary. I wish I could have seen photos of where all those chips are being used (applications), rather than actual memory chips (which, you know, look kinda same)
Is the tech insights article new? The information seems disconnected with other reports. Example is actual definition on 19nm was changed by toshiba. Remember there is both an x and a y :-). Samsung nodes have been multiple between 26nm and 19nm (per techinsights).
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.
