EEPROM stands for electrically erasable programmed memory (EPROM). It is a permanent CMOS memory chip that is utilized in computers and some other electronic devices to store data. It can be programmed using individual bytes that are accessible via an address. Each byte can be either a 1 or a 0. When a 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 from the control gate tunnels into the silicon oxide and reaches the floating gate. This causes electrons to flow in to the gate and get trapped. This causes the gate to alter its content from a zero to a 1. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

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

There are a few methods to reprogram an EEPROM. However, most of them require that the car to be in a certain state. For example, it may be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to the test board. The contents of the EEPROM chip can be read by an EEPROM Reader and copied to another chip.
