EEPROM is an acronym for electrically erasable programmed memory (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It is programmed to store individual bits of data that can be accessed using an address. Each byte can be either 1 or 0. When a byte has been written to the chip, it is activated. The bits are then converted into instructions when the byte is read.

When writing into an EPROM the source and drain are grounded. A high voltage from the control gate passes into the silicon oxide and reaches the floating gate. This causes electrons to flow in to it and become trapped. This causes the gate's content to change from a 0 to one. When the voltage is cut off the gate ceases to be charged 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 are also used to maintain state between power changes. This is especially crucial for ICs that are powered by battery, since a sudden power loss will cause the chip to reset.

There are several ways to reprogram an EEPROM. However, most of them require that the car to be in a particular state. It may be necessary, for example to disconnect the battery and ECU or to remove the chip and place it on an test board.
