Samsung Announces High-density NAND Flash for Mobile Devices

Samsung Electronics has announced two high-density memory solutions for mobile devices. The new storage solutions – a 64-gigabyte (GB) moviNAND memory device and a 32GB micro secure digital (microSD) memory card.

“Samsung’s high-density memory solutions bring the storage capacity levels of computing systems to small, mobile devices,” said Dong-Soo Jun, executive vice president, memory marketing, Samsung Electronics. “The 64GB embedded memory, moviNAND, and the 32GB microSD card each greatly expand the data storage density of mobile devices, meeting customers’ memory requirements and ushering in a new era of mobile and IT device capacity growth.”

The memory solutions are based on Samsung’s advanced 32 gigabit (Gb) NAND flash. The 64GB moviNAND, which measures 1.4mm in height, consists of 16 30nm-class 32Gb MLC NAND chips and a controller. The 17-die stack was achieved by using 30-micron thick chips and advanced package technology. With the new 64GB solution, Samsung's proprietary embedded memory, moviNAND, is now available in 64GB, 32GB, 16GB, 8GB and 4GB densities.

The 32GB microSD card, developed this month, stacks eight 32Gb NAND components and a card controller. The industry’s highest capacity, production-ready microSD card is enabled by the use of Samsung’s advanced 30-nm class 32Gb NAND flash memory technology. Previously, the highest density microSD card in production had a 16GB capacity and was based on 40nm-class 16Gb NAND. The new 32GB card is 1mm-thick. The portion of the card that is inserted into a handset measures just 0.7 mm in height.

Samsung’s new 64GB moviNAND has been in mass production from December 2009, while the 32GB microSD is now being sampled with OEMs, with mass production expected next month.
