The proprietary Sony Memory Stick was first introduced by Sony in October 1998 and is a flash memory card used with Sony digital cameras and other Sony products. Sony released several models of the Memory Stick, including the Memory Stick PRO, Memory Stick Duo, Memory Stick PRO Duo, Memory Stick Micro (M2), and Memory Stick PRO-HG. The capacity of Memory Sticks range in size from 4 MB to 256 GB, with a theoretical maximum capacity of 2 TB.
Today, Sony digital cameras use SD and SDHC memory cards and, with no new cards being released since 2010, the Sony Memory Stick will most likely be discontinued. The picture shows some examples of the different types of Sony Memory Sticks.
