A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices.
Flash drives primarily use NAND flash memory as their storage component. This type of non-volatile memory retains data even when power is turned off, making it ideal for portable storage. Additionally, flash drives contain a USB interface controller that manages data transfer between the flash memory and the host device.
NAND Flash is a special form of Flash memory. Flash memory is a memory technology that keeps data even when the power supply is cut off; this is known as a non-volatile memory type. Flash memory can be read pretty fast, but writing to Flash memory is pretty slow compared to many other -volatile- memory technologies such as SRAM or DRAM. Flash also has a limited number of write-cycles; manufacturers typically specify something in the area of 10,000 writes for the lifetime of the part. NAND Flash is faster than regular Flash, although the general characteristics still hold. Flash memory is widely used in digital cameras, portable MP3 players, USB (Flash) sticks, and many other devices. For more information visit the Related Link.
