The EEPROM Method

The EEPROM is an electrically erasable read-only memory programmable (EPROM). It is a permanent CMOS memory chip that is utilized in computers and other electronic devices to store information. It can be programmed to store individual bytes which can be accessed via an address. Each byte can be either a 1 (or an 0). When the byte is written to the chip it becomes active and when it is read, the bits are decoded into instructions.

When writing to an EPROM, the source and drain terminals are grounded. A high voltage from the control gate passes into the silicon oxide and reaches the floating gate. This causes electrons to flow in to it and then become trapped. The gate's contents to change from a 0 to 1. If 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 are also utilized to maintain the state of the system between power-related transitions. This is crucial for ICs powered by batteries, since a sudden loss of power will 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 certain state. It may be necessary, for instance, to disconnect the battery and ECU or remove the chip and solder it onto an test board. The contents of the EEPROM chip can be read with an EEPROM Reader and copied onto another chip.
