Memory Cards And Their Many Uses

A memory card or flash memory card is a solid state electronic flash memory data storage device used with digital cameras, handheld and laptop computers, telephones, music players, video game consoles, and other electronics. They offer high re-record ability, power free storage, small form factor, and rugged environmental specifications. There are also non solid state memory cards that do not use flash memory, and there are different types of flash memory. They are sometimes called mem-cards by gamers or techies.

There are many different types of memory cards and jobs they are used for. Some common places include in digital cameras, in game consoles, in cell phones, and in industrial applications. PC cards were among first commercial memory card formats to come out in the nineteen nineties, but are now only mainly used in industrial applications and for input/output jobs, as a connection standard for devices, such as a modem. Also in the nineteen nineties, 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 were used in cell phones, game consoles started using proprietary memory card formats, and devices like PDA and digital music players started using removable memory cards.

From the late nineteen nineties into the early two thousands a host of new formats appeared, including SD/MMC, Memory Stick, xD Picture Card, and a number of variants and smaller cards. The desire for ultra small cards for cel phones, PDA, and compact digital cameras drove a trend toward smaller cards that left the previous generation of compact cards looking big. In digital cameras SmartMedia and CompactFlash had been very successful, in the year two thousand and one SM alone captured fifty percent of the digital camera market and CF had a strangle hold on professional digital cameras. By two thousand and five 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, xD, as well as CompactFlash. In industrial fields, even the venerable PC card memory cards still manage to maintain a niche, while in cel phones and PDA, the memory card market is highly fragmented.

Many video game consoles have used proprietary solid state memory cards to store data, especially since games started being distributed in read only optical discs. Nowadays, some new PCs have built in slots for a variety of memory cards. Some digital gadgets support more than one memory card to ensure compatibility.
