A flash memory is a solid-state, non-volatile electronic memory device. It is used in a wide range of electronic devices such as computers (BIOS chips), MP3 players, video game consoles (memory cards), USB flash drives, mobile phones, and digital cameras (memory chips, CompactFlash or SmartMedia). Because of its fast read access time and better shock resistance, and because it is a low-cost, high-speed, high-density, low-power and a highly reliable memory device, it is a very widely used memory storage device. They also do not need any external power source.
USB flash memory is a kind of flash memory with its own memory storage capacity. It is a NAND-based flash memory that offers up to 8 gigabytes of data storage capacity. A USB flash memory drive is very lightweight, small, and durable, and it can be plugged into any computer that has an USB port. It also does not have any moving internal parts, which makes it very portable. USB drives are also referred to as thumb drives, pen drives, USB keys, or flash drives. Most USB memory drives are compatible with Windows 98/ME/2000/XP, Macintosh, Linux, Unix, and other operating systems, depending upon the kind of drive. However, Windows needs a separate drive for hosting different kinds of USB flash memory drives. USB flash memory can support write-erase cycles only to a certain extent, but this can be as high as several million cycles.
A USB memory drive has a printed circuit board incorporated in a plastic or metal casing. It is linked to the computer by attaching the connector to the computer’s USB port or hub. The main parts in a USB drive are a male type-A USB connector (interface to the host computer), USB mass storage controller, a NAND flash memory chip (for storing data), and a crystal oscillator. It can also have jumpers and test pins, a write-protect switch, LEDs, connector cover or cap, and transport aid.
