Method of EEPROM

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

When writing to an EPROM the source and drain are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it reaches the floating gate. This causes electrons to flow in to it and then become trapped. This causes the gate to change its content from a 0 into a 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations and the status of remote keyless systems components. They can be utilized to maintain the state of the system between power-related transitions. This is essential for ICs powered by batteries, as a sudden loss of power can cause the chip to reset.

There are several methods to reprogram an EEPROM. However, most of them require the car to be in a particular state. It might be necessary, for instance to disconnect the battery and ECU or remove the chip and solder it onto the test board. The contents of the EEPROM chip can be read with an EEPROM Reader and copied onto another chip.
