computers and other electronic devices It can be programmed with individual bytes that are accessed using an address Each byte may be 1 or 0 When the byte is written on the chip it becomes active and when it is read the bits are decoded to give instructions When writing into an EPROM the source and drain are grounded A high voltage from the control gate passes through the silicon oxide and gets to the floating gate This causes electrons to flow to it and then become trapped This causes the gate to alter its content from a 0 into a 1 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 be used to maintain state between power transitions This is especially crucial for ICs that are powered by batteries because a sudden loss of power can cause the chip to reset There are a few methods to reprogram an EEPROM However most of them require the car to be in a particular state For instance it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to the test board Then the contents of the EEPROM can be read with an EEPROM reader and copied to a different chip It can be a lengthy process and it can be difficult to find the right information The
