Samsung Electronics develops removable thumbnail-sized flash memory card
Posted on 14-Dec-2004 08:08 | Filed under: News

Samsung announced that it has developed an extremely small, low-power multimedia memory card (MMC) for mobile phones. The Samsung MMCmicro memory card has been designed to overcome a major hurdle in cell phone design -- achieving high performance with a low-power, removable memory card, now smaller than the size of a thumbnail.

With dimensions of only 12x14x1.1mm, Samsung's new "MMCmicro" device is one-third the size of today's common reduced-size multimedia cards (RS-MMC). Samsung said that the design of its low-power card makes it easy to incorporate removable memory into progressively smaller mobile phones. Each card can operate on 1.8 or 3.3 volts of power.

The card can read at 10MB per second and write at 7MB per second; a 128MB version can store about 60 5-megapixel digital photographs or nearly one hour of QVGA-resolution video. Samsung says the card can be erased and reused at least 100,000 times and offers an operating speed between card and system of 26MB per second.

Samsung can stack up to five NAND flash memory devices into each of the new ultra-small memory cards. Initially, they will be sold in 32, 64 and 128 Mbyte sizes. The company expects to begin mass production of its thumbnail-sized memory cards in early 2005.
