WORKING OF PEN DRIVER

USB pen driver are NAND type flash memory data storage devices integrated with a USB (universal serial bus ) interface to access the data stored in a flash drive , the driver must be connected to a computer ,either by plugging it into a USB host controller built into the computer or into USB hub , flash driver(OR)pen driver are ac hive only when plugged into a USB connection and draw all necessary power from the supply provided by that connection.

1.male type-A USB connection.provides an interface to the host computer.

2. USB mass stage controller-implements the USB host controller and provides a linear interface to block oriented serial flash devices while hiding the complexities of block- orientation, block erasure, and wear leveling ,or wear balancing,the controller contains a small amount of on chip ROM and RAM.

3.flash memory chip - stores data .NAND flash is typically also used in DIGITAL CAMERA.

4.crystal oscillator-produces the device's main 12MHZ CLOCK SIGNAL

USING OF USB FLASH DRIVE:-
