Memory Stick Micro M2 Memory Guide

The Memory Stick Micro (M2) was developed as a joint effort by both SanDisk and Sony, and released in 2006. This is the smallest Memory Stick Format currently available. It measures about 15mm x 12.5mm x 1.2mm - roughly the size of a fingernail and about a quarter of the size of the Memory Stick Duo. The Micro is currently available in seven different capacities; 128MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, and 8GB. It has a maximum transfer speed is 160 Mbps. The Micro supports two voltages (dual-voltage) 1.8V, and 3.3V.

Much like the Duo and PRO duo sticks, the Micro can be used with an adapter. The adapter allows compatibility with a Memory Stick PRO slot. Not all devices compatible with a Memory Stick PRO will be compatible with a Micro card in an adapter. Larger capacity Micro cards may also cause problems in older devices. (For example, Some Sony Cile PDAs will not work will cards over 2 GB).

The Memory Stick Micro is most commonly used in cellular phones due to it's small size, and it's it's availability in lower voltages. The increasing popularity of the use of cellular phones as portable music players, cameras, video recorders has caused many consumers to expand their cell phone memory. They are also used commonly used in PDAs to expand storage space. They are versatile and able to store many file types, such as music, images, and video.
