Method of EEPROM

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a nonvolatile CMOS chip which is used to store data in computers and other electronic devices. It can be programmed with individual bytes, which are accessible via an address. Each byte can be either a 1 or a 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 drain and source terminals are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This allows electrons to flow to it and then become trapped. The gate's contents to change from a 0 to a 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 can also be used to keep the state of the system between power transitions. This is important for ICs powered by batteries, as a sudden loss of power can cause the chip to reset.

There are a few methods to reprogram an EEPROM. However, the majority of them require the vehicle to be in a particular state. For example, it may be necessary to disconnect the ECU from the battery, or to remove the EEPROM and connect it to a test board. The contents of the EEPROM chip can then be read by an EEPROM Reader and copied to another chip.

Professionals can accomplish this task swiftly, often within less than an hour.

Certain cars might require an extended procedure to complete, which can be accomplished by connecting the device to the OBD2 port.
