It is a permanent CMOS chip that stores data in computers and other electronic devices. It is programmed to store individual bits of data that can be accessed using an address. Each byte may be a 1 or a 0. When the byte is written on the chip, it becomes active and when it is read the bits are decoded into instructions. When writing to an EPROM the source and drain are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This allows electrons to flow to the gate and get trapped. The gate's contents to change from a zero to 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 system components. They can also be used to preserve status between power changes. This is particularly important for ICs that are powered by batteries because 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 vehicle be in a particular condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery or remove the EEPROM and then connect it to the test board.
