The EEPROM Method

The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers as well as other electronic devices to store data. It is programmed to store individual bits of data that can be accessed using an address. Each byte can be either a 1 or a 0. When a byte has been recorded to the chip it becomes active. The bits are encoded 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 tunnels through the silicon oxide to the floating gate and causes electrons to flow into it and then become trapped. This causes the gate to alter its content from a 0 into a 1. When the voltage is cut off the gate ceases to be charged, and the contents of the EEPROM are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components. They can also be used to keep track of state between power transitions. This is essential 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, most of them require that the car to be in a certain state. It may be necessary, for instance to disconnect the battery and ECU or remove the chip and then solder it to the test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and then copied onto another chip.
