Memory Stick

Memory Stick is a removable flash memory card format, launched by Sony in October 1998, and is 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 file transfer speeds; Memory Stick Duo, a small-form-factor version of the Memory Stick (including the PRO Duo); and the even smaller Memory Stick Micro (M2). In December 2006, Sony added the Memory Stick PRO-HG, a high speed variant of the PRO to be used in high-definition video and still cameras. Memory Stick cards can be used in Sony PSP, Sony XDCAM EX camcorders via the MEAD-SD01 adapter. SanDisk and Lexar are among few third-party Memory Stick producers. Kingston offers universal microSD to Memory Stick Pro Duo adapters, but these are unofficial.

Memory stick, or thumbdrive can refer to most forms of interchangeable flash memory.
