The bits are decoded into instructions when the byte is read.

When writing to an EPROM the drain and source are grounded. A high voltage channeled from the control gate travels through the silicon oxide to the floating gate which causes electrons to flow through it and then become trapped. The gate's contents to change from a 0 to one. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are often used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components. They can be used to keep track of state 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 however, the majority of them require that the car be in a specific state at the time. For instance, it might be necessary to disconnect the ECU from the battery or remove the EEPROM and then connect it to a test board.
