used in computers and some other electronic devices to store data It can be programmed to store individual bits of data that are accessed with an address Each byte could be one or zero If a byte has been written to the chip it becomes active The bits are then decoded into instructions when the byte is read When writing to an EPROM the source and drain are grounded A high voltage channeled from the control gate travels through the silicon oxide and into the floating gate which causes electrons to flow into it and then become trapped This causes the gates content to change from a 0 to one If 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 and the status of remote keyless system components They are also utilized to maintain the state of the system between power transitions This is especially important for ICs that are powered by batteries because a sudden loss of power can cause the chip to reset There are a couple of methods to reprogram an EEPROM However the majority of them require the car to be in a particular state It might be necessary for
