The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a nonvolatile CMOS memory chip used in computers and other electronic devices to store information. It can be programmed to store individual bytes that can be accessed using an address. Each byte may be a 1 or a 0. When a byte has been recorded to the chip it becomes active. The bits are converted into instructions when the byte is read.

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

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations, and the status of remote keyless systems components. They can be used to keep track of state between power transitions. This is particularly important for ICs that are powered by battery, because a sudden loss of power can cause the chip to reset.

There are a few ways to reprogram an EEPROM however, the majority of them require that the car be in a particular condition at the time of. It might be necessary, for instance, to disconnect the ECU and battery or to take the chip off and solder it onto an test board.
