With the proliferation of portable electronic devices such as the digital camera and the PDA (personal digital assistant), a significant market has arisen in the manufacturing of memory cards. Memory cards have shown to be the popular means by which data is stored and transferred among this latest generation of portable device. The size and convenience of memory cards is complimented by the large amount of data that can be stored on such a small item.

Until recently, portable devices were limited by the amount of onboard memory power. A digital camera could only hold a relatively small amount of pictures of decent quality. The solution to this lack of onboard memory was the utilization of removable memory cards which could be swapped and stored. Now containing upwards of 1GB of memory, some of these cards may never even need to be removed to satisfy their owner's needs!

Different Formats for Memory Cards

As is often the case with burgeoning technologies, there are several different types of memory cards. They function in a similar fashion; more often than not, you can simply press a card into a given slot on your device, and data is encoded onto the card. The connections and technical means of storage are different for each format, but the result is the same: increased memory and storage.

The most popular formats for memory cards these days are CompactFlash cards and SmartMedia cards. Several different types of device use each of these formats. Some devices use their own proprietary formats for memory cards. It is vital that you know what type of memory card your device uses before you spend money to buy a card.
