The EEPROM Method The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a nonvolatile CMOS memory chip used in computers and other electronic devices to store data. It can be programmed using individual bytes, which are accessible via an address. Each byte could be one or zero. When 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 channeled from the control gate travels through the silicon oxide and into the floating gate which causes electrons to flow into it and get trapped. This causes the gate to alter its content from a 0 into a 1. If the voltage is removed, the gate becomes uncharged and the contents of the EEPROM are erased. EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations and the status of remote keyless systems components. They can also be used to keep the state of the system between power transitions. This is especially crucial for ICs that are powered by batteries because a sudden loss of power will cause the chip to reset. There are a variety of ways to reprogram an EEPROM however, the majority of them require that the vehicle be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery, or to remove the EEPROM and then connect it to an test board. Then the contents of the EEPROM can be read by an EEPROM reader and copied to a different chip. It can be a time-consuming procedure, and it's difficult to get the right information. The majority of people prefer having their vehicles reprogrammed by professionals rather than trying this at home.
