Method of EEPROM EEPROM stands for electrically erasable programmable memory (EPROM). It is a non-volatile CMOS chip that stores data in computers as well as other electronic devices. It is programmed to store individual bytes which can be accessed via an address. Each byte may be a 1 or a 0. When a byte is written to the chip, it is activated, 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 channeled from the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow into it and get trapped. This causes the gate's content to change from a 0 to 1. If the voltage is removed the gate ceases to be charged and the contents of the EEPROM are erased. EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless systems components. They can also be utilized to maintain the state of the system between power-related transitions. This is especially crucial for ICs that are powered by battery, since a sudden loss of power could cause the chip to reset. There are a few ways to reprogram an EEPROM however, the majority of them require that the car be in a certain condition at the time of. For example, it may be necessary to disconnect the ECU from the battery, or remove the EEPROM and solder it to an test board. The contents of the EEPROM chip can then be read with an EEPROM Reader and copied to another chip. It is a lengthy process, and it can be difficult to get the right information. Most people prefer to have their vehicles reprogrammed by professionals rather than trying this at home. Find a reputable auto locksmith with sophisticated tools who understands what they are doing.
