Method of EEPROM

EEPROM stands for electrically erasable programmed memory (EPROM). It is a nonvolatile CMOS memory chip that is utilized in computers and other electronic devices to store information. It can be programmed with individual bytes, which can be accessible using an address. Each byte is either 1 (or an 0). If a byte has been written to the chip it is activated. The bits are then decoded into instructions when the byte is read.

When writing into an EPROM the source and drain are grounded. A high voltage from the control gate passes through the silicon oxide and reaches the floating gate. This allows electrons to flow to it and then become trapped. This causes the gate to change its content from a zero to a 1. When 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 system components. They are also used to maintain state between power changes. This is especially important for ICs that are powered by battery, since a sudden loss of power can cause the chip to reset.

There are a few ways to reprogram an EEPROM. However, most of them require that the car to be in a specific state. For instance, it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to the test board. Then, the contents of the EEPROM can be read using an EEPROM reader and copied to another chip.

A professional can complete this task efficiently, 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.
