It is programmed to store individual bytes which can be accessed via an address. Each byte is either 1 (or an 0). If a byte has been written to the chip, it becomes active. The bits are then decoded into instructions when the byte is read.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate tunnels through the silicon oxide and reaches the floating gate. This causes electrons to flow to it and become trapped. This causes the gate to change its contents from a zero to a 1. If the voltage is removed, the gate becomes uncharged and the contents of the EEPROM are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components. They can also be used to preserve status between power changes. This is important for ICs powered by batteries as a sudden loss of power will cause the chip to reset.

There are a couple of ways to reprogram an EEPROM. However, most of them require the car to be in a specific state. For example, it may be necessary to disconnect the ECU from the battery or to remove the EEPROM and connect it to the test board. The contents of the EEPROM chip can be read by an EEPROM Reader and then copied onto another chip.
