chip that is used to store data in computers as well as other electronic devices It can be programmed using individual bytes which are accessed using an address Each byte is either 1 or a 0 When the byte is written on the chip it is activated and when it is read the bits are decoded as instructions When writing into an EPROM both the drain and source are grounded A high voltage from the control gate tunnels into the silicon oxide before it reaches the floating gate This allows electrons to flow to it and then become trapped This causes the gate to change its contents from a zero to a 1 When the voltage is removed the gate is uncharged and the contents of the EEPROM are erased EEPROMs are typically used to store calibration coefficients for sensors bootloader configurations and also the status of remote keyless system components They are also used to keep track of state between power changes This is crucial for ICs powered by batteries because a sudden loss in power will cause the chip reset There are a few methods to reprogram an EEPROM however the majority of them require that the car be in a particular condition at the time of For instance it might be necessary to disconnect the ECU from the battery or remove the EEPROM and connect it to an test board Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip This can be a lengthy
