EEPROM is an acronym for electrically erasable programmed memory (EPROM). It is a non-volatile CMOS chip that is used to store data in computers as well as other electronic devices. It is programmed to store individual bytes which can be accessed via an address. Each byte may be one or zero. When the byte is written to the chip, it is activated and, when it is read, the bits are decoded to give instructions.

When writing to an EPROM the drain and source are grounded. A high voltage from the control gate passes into the silicon oxide and gets to the floating gate. This causes electrons to flow in to it and then become trapped. This causes the gate to change its contents from 0 to 1. When the voltage is cut off the gate ceases to be charged, and the contents of the EEPROM are erased.

EEPROMs are often used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to keep state between power transitions. This is especially important for ICs that are powered by batteries since a sudden power loss can cause the chip to reset.

There are a variety of methods to reprogram an EEPROM, but most of them require that the car be in a specific condition at the time of. It could be necessary, for instance, to disconnect the ECU and battery or to take the chip off and then solder it to an test board.
