Samsung Electronics has developed an 8GB micro memory card for smartphones.

The microSD (Secure Digital) card boasts the highest capacity for a microSD card, Samsung said. The card is capable of storing 2,000 MP3 music files, 4,000 digital photos or about five DVD-quality movies. The card has a read/write speed of 16MB/sec. and 6MB/sec, respectively.

The microSD card, about a quarter the size of a standard SD card used in cameras, is backward compatible with SD cards using an extender to allow multimedia files downloaded by mobile phones to be displayed on other media.
