The SD Memory Card is the latest and most advanced representative of a type of data storage known as flash memory. If you own a digital camera or a portable MP3 audio player, you are probably already familiar with this technology. The small size, low power consumption, and solid-state design of flash-memory cards have made them very popular for use in such products.

Panasonic is one of the co-developers of the SD Memory Card, which incorporates refinements and features that will greatly expand the range of applications for flash memory. And as SD consolidates its position as the de facto standard for flash memory cards, the growth of applications will accelerate. SD, or Secure Digital, Memory Card boasts a number of compelling advantages over other formats.
