Definition: Flash memory is the storage medium used with digital cameras. The flash memory card can retain the stored data without the need for continual power. Several different brands of flash memory cards, also called memory cards, exist, and digital cameras can only use specific brands. Each brand is a different size, and memory cards are not interchangeable.

Flash memory is not related to the flash unit of artificial light that your digital camera uses to illuminate a dark scene before shooting a photo.
