bytes which can be accessed via an address Each byte can be either a 1 or a 0 If a byte has been written to the chip it becomes active The bits are then encoded into instructions when the byte is read When writing to an EPROM the source and drain terminals are grounded A high voltage that is channeled from the control gate tunnels through the silicon oxide and into the floating gate and causes electrons to flow into it and get trapped The gates contents to change from a 0 to one When the voltage is removed from the gate it becomes uncharged and the EEPROM contents 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 the state of the system between power transitions This is important for ICs powered by batteries since a sudden loss of power will cause the chip to reset There are a few ways to reprogram an EEPROM However the majority of them require that the car to be in a specific state It could be necessary for instance to disconnect the battery and ECU or remove the chip and solder it onto the test board Then the contents of the EEPROM
