EEPROM stands for electrically erasable programmed memory (EPROM). It is a permanent CMOS memory chip that is used in computers and other electronic devices to store data. It can be programmed with individual bytes, which can be accessible via an address. Each byte is either 1 (or a 0). When a byte has been written to the chip, it becomes active. 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 gets to the floating gate. This causes electrons to flow in to the gate and get trapped. The gate's contents to change from a 0 to 1. If the voltage is removed the gate is uncharged and the contents of the EEPROM are erased.
EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be used to maintain status between power changes. This is essential for ICs powered by batteries as a sudden loss of power can cause the chip to reset.
There are several ways to reprogram an EEPROM. However, the majority of them require that the car to be in a particular state. It might 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 by an EEPROM Reader and copied onto another chip.
