Samsung is the world's biggest supplier of NAND flash memory and
has been developing higher density memory solutions for mobile
devices. The company is announcing a 64GB 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, the Executive Vice President of Memory Marketing
for 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," he added.
The new solutions are based on Samsung's 32gb NAND chips. The 64GB
moviNAND is only 1.4mm high, and 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 moviNAND embedded memory is now
available in 64GB, 32GB, 16GB, 8GB and 4GB densities.
32GB microSD card stacks eight 32Gb NAND components and a card
controller. The highest capacity microSD card currently in production
has a 16GB capacity and is based on 40nm-class 16Gb NAND. The new
32GB card is only 1mm thick.
Samsung's new 64GB moviNAND
has been in mass production since December, while the 32GB microSD
cards are currently sampling with mass production expected next
month. These will compete against similar
offerings from Toshiba announced last month.
