Techopedia Explains Memory Card

A memory card is mainly used as a primary and portable flash memory in mobile phones, cameras and other portable and handheld devices. PC Cards (PCMCIA) were a predecessor of modern memory cards that were introduced for commercial purposes. Besides providing non-volatile media storage, a memory card also uses solid state media technology, which lowers the chances of mechanical problems, such as those found in traditional hard drives.

Some of the most popular forms of memory cards are:

  • Secure Digital (SD) card
  • CompactFlash (CF) card
  • SmartMedia
  • Memory Stick
  • MultiMediaCard (MMC)
