Method of EEPROM

EEPROM is an acronym for electrically erasable memory that is programmable (EPROM). It is a permanent CMOS chip that is used to store data in computers and other electronic devices. It can be programmed with individual bytes, which can be accessible via an address. Each byte is either a 1 (or a 0). When a byte is written to the chip, it is activated, and when it is read, the bits are decoded as instructions.

When writing into an EPROM the drain and source are grounded. A high voltage channeled from the control gate travels through the silicon oxide to the floating gate, causing electrons to flow into it and become trapped. This causes the gate's content to change from a 0 to a 1. If the voltage is removed the gate ceases to be charged and the contents of the EEPROM are erased.

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to keep state between power transitions. This is crucial for ICs powered by batteries because a sudden loss in power can cause the chip to reset.

There are a variety of ways to reprogram an EEPROM, but most of them require that the car be in a specific condition at the time of. It may be necessary, for example to disconnect the battery and ECU or remove the chip and then solder it to the test board. Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip.

A professional can complete this quickly, often within an hour.

Certain cars might require a longer process that can be completed by connecting the device to the OBD2 port. Certain cars may even require EEPROM programming procedures, which can take days.
