Method of EEPROM
The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a nonvolatile CMOS memory chip used in computers as well as other electronic devices to store information. It is programmed to store individual bits of data that are accessed with an address. Each byte may be one or zero. When the byte is written on 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 tunnels through the silicon oxide and reaches the floating gate. This causes electrons to flow to it and then become trapped. This causes the gate's content to change from a 0 a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.
EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless systems components. They can also be used to preserve status between power changes. This is crucial for ICs powered by batteries because a sudden loss in power can cause the chip to reset.
There are a few ways to reprogram an EEPROM. However, most of them require the vehicle to be in a certain state. It could be necessary, for instance, to disconnect the battery and ECU or to take the chip off and place it on a test board. The contents of the EEPROM chip can be read using an EEPROM Reader and then copied onto another chip.
It can be a time-consuming process, and it can be difficult to find the right data. Many people opt to have their cars reprogrammed professionally instead of trying this at home.
