Samsung releases its densest mobile memory card

Samsung today unveiled two high-density memory modules for mobile devices that double the capacity of its previous high-end micro secure digital (microSD) cards.

The new storage offerings include a 64GB moviNAND embedded memory module and a 32GB removable microSD memory card.

The new memory cards are based on Samsung's 32Gbit NAND flash memory chips, which use 30 nanometer lithography technology. The 64GB moviNAND memory module measures 1.4 millimeter in height, contains 16 flash chips and a controller. The new moviNAND memory is also available in 64GB, 32GB, 16GB, 8GB and 4GB densities.

The 32GB microSD card, developed this month, uses eight 32Gbit NAND flash chips and a controller. Previously, the highest density microSD card in production had a 16GB capacity and was based on 40 nanometer lithography technology. The new 32GB card is only 1 millimeter thick, and the portion of the card that is inserted into a mobile device handset measures just 0.7 millimeters in height.

"Samsung's high-density memory solutions bring the storage capacity levels of computing systems to small, mobile devices," Dong-Soo Jun, executive vice president of memory marketing for Samsung Electronics, said in a statement.

Samsung's began mass production of its new 64GB moviNAND in December. The module is now shipping to mobile device manufacturers. The 32GB microSD is now being sampled with OEMs and is expected to be in mass production next month.
