The ultra-small memory card is designed to meet the growing storage needs of highly compact, multifunctional mobile phones. An M2 adaptor in the size of a standard Memory Stick will allow users to exchange data to Memory Stick PRO compatible products. The M2 media is approximately one-quarter the volume of Memory Stick PRO Duo media, yet only about 1.2mm thick. M2 media is designed as an externally removable media with a controlled eject function to prevent users losing the media. Following the trend of mobile phones which operate at 1.8 volts, the M2 has been designed as dual-voltage media. In addition to 1.8 volt support, the media offers 3.3 volt operation which is required for existing Memory Stick PRO compatible products.
