A memory card or flash card is an electronic flash memory data storage device used for storing digital contents. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players, and video game consoles. They are small, re-recordable, and they can retain data without power.
The most common type of memory card in use today is the SD card[1], which comes in capacities of up to 32 Gigabytes. In addition to these and other types of memory cards, there are also non-solid-state memory cards that do not use flash memory, and there are different types of flash memory. Many cards incorporate wear levelling algorithms in their design.
PC Card (PCMCIA) were among first commercial memory card formats (type I cards) to come out in the 1990s, but are now mainly used in industrial applications and to connect I/O devices such as modems. In 1990s, a number of memory card formats smaller than PC Card came out, including CompactFlash, SmartMedia, and Miniature Card. In other areas, tiny embedded memory cards (SID) were used in cell phones, game ds. The desire for smaller cards for cell-phones, PDAs, and compact digital cameras drove a trend that left the previous generation of "compact" cards looking big. In digital cameras SmartMedia and CompactFlash had been very successful, in 2001 SM alone captured 50% of the digital camera market and CF had a strangle hold on professional digital cameras. By 2005 however, SD/MMC had nearly taken over SmartMedia's spot, though not to the same level and with stiff competition coming from Memory Stick variants, as well as CompactFlash. In industrial fields, even the venerable PC card (PCMCIA) memory cards still manage to maintain a niche, while in cell-phones and PDAs, the memory card market is highly fragmented.

Many game consoles have used proprietary solid-state memory cards to store data. In recent years read-only optical discs have replaced these memory cards in most current home console systems. However most portable gaming systems still rely on custom memory cartridges, due to their low power consumption, smaller physical size and reduced mechanical complexity.
The sizes in parenthesis are those of the official, first-party memory cards.

As games moved away from the cartridge format and into CD-ROM, DVD and other read-only media, the place for saving your games became devices called memory cards. These cards plug into your console or controller, and let you save your game files onto them.
While you did have to pay extra now to be able to save a game, memory cards had some benefits. You could take your friends saved games from their memory card. Gone are the days of finding someone else's saved game with a character called "Penis" when you rented some SNES title from a video store.
Without hard drives, memory cards are the main and primary way of storing your saved game data.

A memory card is a form of flash memory that is used in a range of electronic devices such as a digital cameras or video game console. The memory card stores data, images, music, saved games or other computer files.
Flash memory devices like this contain no moving parts so they are not easily damaged. This means that they are ideal for use in portable devices such as MP3 players, digital cameras, mobile phones etc.
The amount of data memory cards can store depends on the capacity of the card. Currently (in 2010) the largest memory cards can store 64 gigabytes of data. As the technology improves, larger capacity cards will become available.
There are many different types of memory cards, for example Secure Digital (SD) or CompactFlash cards.
