Samsung unveils high-performance memory cards for 4G smartphones


Samsung Electronics announced production of its
high-performance micro Secure Digital (microSD) cards with advanced data
transfer speeds that support the performance requirements on fourth generation
(4G) smartphones.


The new 20-nanometer-class microSD cards from Samsung
have a class 10 speed rating suitable for seamless data storage and
transmission of full HD video, one of the features becoming highly popular
among 4G smartphone users.


The industry demand for high-class-rated memory cards
addresses the growing performance push for next generation mobile applications
in more advanced smartphones including 4G models,” said Wanhoon Hong,
executive vice president, memory sales & marketing, Samsung Electronics.


As the industry adopts microSD cards with a class 10
rating, the superior data transfer speeds are expected to improve the mobile
user experience tremendously,” Hong added.


The new 32GB microSD cards can write at 12 megabytes per second (MB/s) and read at 24MB/s,
providing users with more than double the maximum write speeds of a class 4
rated 32GB microSD card. The new 32GB memory card incorporates 32Gb 3-bit NAND
flash memory chips and a proprietary 3-bit NAND controller to deliver the high


The new card follows the introduction of Samsung’s 30
nanometer (nm) class, 32 gigabit (Gb) 3-bit-per-cell (3-bit) NAND-based 32
gigabyte (GB) microSD cards in February 2010. By applying the finer 20-nm-class
process technology, the productivity of the chips is raised over 30 percent.


As an industry pioneer, Samsung plans to continue to
aggressively introduce new NAND-based mobile memory solutions for timely market
adoption. Mass production of its 20nm-class 64Gb 3-bit NAND designed on
advanced toggle NAND architecture is anticipated for early next year.
