When the byte is written on the chip, it becomes active and, when it is read the bits are decoded to give instructions.

When writing data into an EPROM, both the drain and source are grounded. A high voltage that is channeled from the control gate travels through the silicon oxide to the floating gate and causes electrons to flow into it and become trapped. This causes the gate to change its content from 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 save the calibration coefficients of sensors, bootloader configurations and the status of remote keyless system components. They can also be used to maintain status between power changes. This is crucial for ICs powered by batteries as a sudden loss of power will cause the chip reset.

There are a variety of methods to reprogram an EEPROM, but most of them require that the vehicle be in a certain condition at the time of. For instance, it might be necessary to disconnect the ECU from the battery or to take the EEPROM out and solder it to the test board.
