A memory card, flash card or memory cartridge is an electronic flash memory data storage device used for storing digital information. These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, and digital pianos.

More and more data today is stored using flash based memory from digital camera memory sticks, SmartMedia and SD memory cards to USB/Firewire flash drives and Solid State Drives.

Flash drives, like other forms of storage media, have grown in capacity at cheaper costs in a portable package.
