When the byte is written on the chip it becomes active cut and program car key when it is read, the bits are decoded as instructions.

When writing to an EPROM the source and drain terminals are grounded. A high voltage from the control gate passes into the silicon oxide and gets to the floating gate. This causes electrons to flow to the gate and get trapped. This causes the gate to change its contents from 0 to 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations and the status of remote keyless system components. They can be used to keep track of state between power transitions. This is especially crucial for ICs that are powered by batteries, because a sudden loss of power can cause the chip to reset.

There are a few ways to reprogram an EEPROM however the majority of them require that the vehicle be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and connect it to an test board.
