Tunnel injection
Encyclopedia
Tunnel injection is the quantum tunneling effect, also called Fowler-Nordheim tunnel injection, when charge carrier
s are injected to an electric conductor through a thin layer of an electric insulator.
It is used to program NAND flash memory
. The process used for erasing is called tunnel release.
An alternative to tunnel injection is the spin injection.
Charge carrier
In physics, a charge carrier is a free particle carrying an electric charge, especially the particles that carry electric currents in electrical conductors. Examples are electrons and ions...

Flash memory
Flash memory is a non-volatile computer storage chip that can be electrically erased and reprogrammed. It was developed from EEPROM and must be erased in fairly large blocks before these can be rewritten with new data...
