When the byte is written to the chip, it is activated, and when it is read, the bits are decoded as instructions.

When writing data into an EPROM the drain and source are grounded. A high voltage channeled from the control gate tunnels through the silicon oxide and into the floating gate, causing electrons to flow into it and become trapped. This causes the gate's content to change from a 0 to 1. When the voltage is cut off the gate ceases to be charged and the contents of the EEPROM are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless systems components. They can also be used to keep state between power transitions. This is crucial for ICs powered by batteries because a sudden loss in power can cause the chip to reset.

There are a variety of methods to reprogram an EEPROM however, the majority of them require that the vehicle be in a specific condition at the time of. It could be necessary, for example to disconnect the battery and ECU or to take the chip off and place it on the test board.
