Floating gate and charge trap

In a charge trapping flash, electrons are stored in a trapping layer just as they are stored in the floating gate in a standard flash memory, EEPROM, or EPROM. The key difference is that the charge trapping layer is an insulator, while the floating gate is a conductor.
