CompactFlash in the context of Mass storage device

A memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices, such as digital cameras as well as in many early games consoles such as the Neo Geo. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives.

Common types of flash memory card include SD cards (including microSD), Sony's Memory Stick and CompactFlash. As of 2024, SD cards are the most common type of memory cards.

Cyber-shot is Sony's line of point-and-shoot digital cameras introduced in 1996. Cyber-shot model names use a DSC prefix, which is an initialism for "Digital Still Camera". Many Cyber-shot models feature Carl Zeiss trademarked lenses, while others use Sony, or Sony G lenses.

All Cyber-shot cameras accept Sony's proprietary Memory Stick or Memory Stick PRO Duo flash memory, except the DSC-MD1 which only accept MiniDisc. Select models have also supported CompactFlash. Current Cyber-shot cameras support Memory Stick PRO Duo, SD, SDHC, and SDXC. From 2006 to 2009, Sony Ericsson used the Cyber-shot brand in a line of mobile phones.
