Samsung today 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 – satisfy mobile handset designers’ requirements for advanced compact high-density memory.

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.

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.
