Memory Stick is a removable flash memory card format, used mostly in Sony portable hardware.

Variations 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). The Memory Stick is defined in the minds of many by its proprietary nature, as the majority of portable devices that use it are Sony and Sony Ericsson devices.

Memory stick is read or written by half-duplex serial protocol of three-wire system. Write speed is 1,800MB - 330KB/s. Depends on flash memory cell. Read speed is 2.45MB/s.
