What is Memory stick?

Memory sticks is a removable flash memory card format, launched by Sony in October 1998, and also used in general to describe the whole family of Memory sticks. In addition to the original memory stick, this family includes the Memory Stick PRO, a revision that allows greater maximum storage capacity and faster transfer speeds; Memory Stick Duo, a small-form factor version of the memory stick (including the PRO Duo); and the even smaller Memory Stick (M2). In December 2006 Sony added the Memory Stick PRO-HG, a high speed variant of the PRO, to be used for high definition still and video cameras.

Normally memory sticks are used for data storage & transportation of portable devices such a digital camera, PDA’s, Cell phones, Play Station Portable (PSP), which can be later accessed by a personal computer for retrieval and permanent storage of data. For example, with a e\memory stick a user can transfer photographs clicked on a digital cameras to its computer through a memory stick reader.
