MicroSD is designed for new mobile phones that are compact yet fully-featured with storage-intensive multimedia applications such as digital cameras, video capture and playback, MP3 players, video games, personal organizers, Multimedia Message Service (MMS), email and voicemail capabilities.
The exceptionally small size of microSD (11mm x 15mm x1mm) represents approximately one quarter of the volume of the smallest removable flash cards available on the market today and allows handset manufacturers to incorporate significant amounts of removable storage capacity into their progressively smaller handsets without changing the physical size of the phone.
MicroSD represents a new type of flash memory for mobile phones that combines the space-saving benefit of embedded flash memory with the flexibility of removable flash storage cards. Given the extremely small size of the microSD module, handset manufacturers have greater flexibility to implement microSD into their new designs. A range of microSD connectors are available that support external slots as well as ‘under-the-battery’ placement.
The microSD module is likely to be used as a semi-permanent storage device in the handset, and is ideal to transport subscriber data and settings from an older microSD enabled phone to a new one. microSD has built- in content protection rights management to allow secure downloads of content such as songs, video clips and video games. Future versions of microSD are being developed which will offer advanced encryption security to permit protected storage of personal, financial and medical information.
When inserted into an available SD adapter, microSD converts into the SD card for interoperability with standard SD devices so consumers can exchange data between their microSD-equipped mobile phone and any SD compatible host, such as a digital camera, PDA or laptop PC.
