Samsung Electronics Co. Ltd disclosed that it has started mass-production of what it claims as the smallest memory card available for mobile phones. The MMC? device can read data at 10MBps and write at 7MBps. According to Samsung, this is 3.5 times faster than competing flash memory cards.

The new thumbnail-sized memory card, designed for mobile phones with advanced multimedia features, can support four NAND flash memory chips and measures 12-by-14-by-1.1mm, which is one-third the size of the reduced size multimedia card (RS-MMC). An external 256MB MMC? card can hold about 120 photographs with a 5Mpixel resolution or 100 minutes of QVGA-quality video.

Multimedia features are increasingly being added to small mobile phones, requiring larger memory capacity and a smaller memory footprint, said Samsung. This puts pressure on mobile phone manufacturers to use memory cards that pack big memory capacity and small size. Research firm Gartner expects the demand for MMC cards to grow an average of 61 percent annually through 2007.

The new MMC? cards can operate on 3.3V or 1.8V, cutting power consumption up to one-sixth that of competing devices, said Samsung. These cards can write, read and be erased more than a hundred thousand times. They are available in 32-, 64-, 128- and 256Mbyte versions. The company shared that it also plans to add a 512MB version to the lineup within the next three months. Meanwhile, a 2GB card that supports four 4Gb NAND flash memory chips will be introduced in the first half of 2006.

Samsung also disclosed that it is working on standardizing MMC? memory card with the Multimedia Card Association (MMCA). These new cards are already available with Samsung's latest mobile phones, including its 5Mpixel and 7Mpixel camera phones.
