Electronically Erasable-Programmable Read Only Memory-A memory device whose content can be established through a programming process (usually the tunneling of electrons across a thin layer of silicon dioxide) to a floating gate. Each memory cell of an EEPROM can be individually erased by imposing a voltage to reverse the flow of electrons to move them away from the floating gate. That cell can then be reprogrammed. Both programming and erasing can be performed without removal of the device from the system in which it is used.
