Method of EEPROM The EEPROM is an electrically erasable programmable read-only memory (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It can be programmed to store individual bits of data that can be accessed using an address. Each byte could be one or zero. When a byte is written to the chip it becomes active and when it is read the bits are decoded into instructions. When writing to an EPROM, the source and drain terminals are grounded. A high voltage channeled through the control gate tunnels through the silicon oxide to the floating gate, causing electrons to flow into it and become trapped. This causes the gate to alter its content from 0 to 1. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased. EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless systems components. They can also be used to keep state between power transitions. This is especially crucial for ICs that are powered by batteries because a sudden loss of power will cause the chip to reset. There are reprogram car key of methods to reprogram an EEPROM. However, most of them require that the car to be in a specific state. It could be necessary, for instance to disconnect the battery and ECU or to remove the chip and place it on the test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and copied onto another chip. It can be a time-consuming procedure, and it's difficult to find the right information. Many people prefer having their cars reprogrammed by experts rather than trying this at home. Find a reputable auto locksmith with advanced tools who know what they are doing.
