A Secure Digital (SD) memory card is a portable flash memory chip used in devices like digital cameras, cellular phones, and audio players. The card is about the size of a postage stamp and comes in various capacities and transfer speeds.
Secure Digital memory cards are significantly smaller than CompactFlash cards, and are equipped with a nine-pin interface as compared to the 50-pin interface of the CompactFlash. The result of having fewer interface pins means that the SD cards are limited to a four-bit data bus, whereas CompactFlash cards have a 16-bit data transfer bus.
