USB flash drive or any other flash memory drive is an EEPROM that means electrically erasable programmable read-only memory. USB flash memory sticks are:
- Nothing but an EEPROM assembly.
- A controller with a RISC microprocessor RAM.
- ROM.
All of this interacts with a computer using a USB controller and connector because USB sticks are EEPROM that can hold data for as long as ten years. UBS thumb usually drives don't require drivers, but with few old operating systems like windows 98 and windows 95, you need drivers provided by the manufacturer.
Latest OS considers USB drives as USB mass storage devices and has built-in support for these drives, which means you don't need any drivers; plug in the drive and start using it. Some Linux versions might recognize it but won't let you use it until you manually mount the drive.
