The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a nonvolatile CMOS chip that is used to store information in computers and other electronic devices. It can be programmed to store individual bytes that are accessed with an address. Each byte can be either 1 or 0. Once a byte is written to the chip, it is activated. The bits are converted into instructions when the byte is read.

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 to the floating gate and causes electrons to flow into it and get trapped. The gate's contents to change from a 0 one. If the voltage is removed the gate is uncharged, 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 systems components. They can be utilized to maintain the state of the system between power changes. This is crucial for ICs powered by batteries as 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 car be in a certain condition at the time of. It could be necessary, for example to disconnect the ECU and battery or to remove the chip and then solder it to an test board.
