Flash memory uses EEPROM (Electronically Erasable Programmable Read Only Memory) chip. There is one in each flash drive. They use a process called Fowler-Nordheim Tunneling, which regulates electron flow to write code (0 or 1) by controlling the electric charge that passes though the flash drive's "floating gate." Flash memory is much faster than other forms of EEPROM because it erases entire blocks of memory at a time, rather than just a byte at a time.
