Samsung today announced two high-density memory solutions for
mobile devices - a 64-gigabyte (GB) moviNAND memory device and a
32GB micro secure digital (microSD) memory card.
The memory solutions are based on Samsung's 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 production-ready
microSD card is enabled by the use of Samsung's 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.
According to market research firm iSuppli, the global NAND flash
memory market for 32GB and higher memory cards is forecast to be
530 million units in 2010 and reach 9.5 billion units by 2013 (in
16Gb equivalent units).
Samsung?s new 64GB moviNAND has been in mass production from
December 2009, while the 32GB microSD is now being sampled, with
mass production expected next month.
