Memory Stick Micro (M2) was the smallest form factor of the Sony Memory Stick family. It was introduced as a joint venture with SanDisk in 2006 and is just one-quarter of the size of the Memory Stick Duo. Typical uses include PDAs and mobile phones.
Adaptors were available to allow Memory Stick Micro cards to be used in Memory Stick and Memory Stick Duo slots, and Sony produced an M2 to USB adaptor.
Cards were available from 64 MB to 16 GB capacities.
In 2009, Sony announced that Sony Ericsson phones would use microSD cards instead of Memory Stick Micro, and by 2011, the Memory Stick Micro was no longer available on the Sony UK website.
