The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a permanent CMOS memory chip that is used in computers and other electronic devices to store data. It can be programmed using individual bytes, which can be accessible using an address. Each byte can be either a 1 (or a 0). When the byte is written to the chip it becomes active and, when it is read, the bits are decoded to give instructions.


When writing to an EPROM, the drain and source terminals are grounded. A high voltage channeled from the control gate travels through the silicon oxide and into the floating gate, causing electrons to flow through it and then become trapped. The gate's contents to change from a 0 one. When the voltage is removed the gate is uncharged 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 maintain the state of the system between power transitions. This is important for ICs powered by batteries since a sudden loss of power can cause the chip to reset.

There are a variety of ways to reprogram an EEPROM however, the majority of them require that the vehicle be in a specific state at the time. For instance, it could be necessary to disconnect the ECU from the battery or to take the EEPROM out and then connect it to the test board.
