Micro Memory Stick
This news is a little old, but since I finally found a picture of it I thought it was worth posting.
Sony and SanDisk create Memory Stick Micro for mobile phones.
The 1.2-millimeter-thick removable flash storage card is one-quarter the size of the Memory Stick Pro Duo media used in devices such as digital cameras and game consoles. It has a theoretical maximum capacity of 32 gigabytes.
