Samsung lancerer hurtigere, højtydende memorykort til 4G smartphones (in english).
Samsung Electronics have 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 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, says 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.
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 performance.
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.
