The bits are decoded into instructions when the byte is read.


When writing into an EPROM the drain and source are grounded. A high voltage channeled from the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow into it and then become trapped. This causes the gate's content to change from a 0 to one. When the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless systems components. They can also be used to preserve the state of the system between power transitions. reprogram car key is essential for ICs powered by batteries, because a sudden loss in power will cause the chip to reset.

There are several ways to reprogram an EEPROM however the majority of them require that the car be in a certain condition at the time of. For instance, it might be necessary to disconnect the ECU from the battery or to take the EEPROM out and solder it to an test board.
