Memory Stick is a proprietary flash media card format developed by Sony, and is used almost exclusively in Sony and Sony Ericsson products. The term memory stick is also used to refer to the combined family of flash memory cards developed and marketed by Sony that include a large number of smaller, faster, and larger capacity cards than the original Memory Stick format. Memory Stick cards measure roughly 50mm x 22mm in size.
