LONDON &$151; Memory chip giant Samsung Electronics Co. Ltd. has announced two memory modules for mobile devices; a 64-Gbyte moviNAND memory and 32-Gbyte micro secure digital (microSD) memory card. The memories are based on Samsung's 32-Gbit NAND flash.

The 64-Gbyte moviNAND measures 1.4-mm in height and consists of 16 of the 32-Gbit MLC NAND chips and a controller. The 17-die stack was achieved by using 30-micron thick chips and advanced package technology.

The 32-Gbyte microSD card stacks eight 32-Gbit NAND components and a card controller. The new 32-Gbyte card is 1-mm thick. The portion of the card that is inserted into a handset measures just 0.7 mm in height.
