Understanding the basics of storage devices used in automobiles
Information including vehicle identification number, immobilization key registration, fuel/air ratio mapping data and more are stored in non-volatile memory, and a typical example is a semiconductor storage device called EEPROM. Understanding this device will be of great help in future vehicle maintenance.

Computer storage is largely divided into volatile memory, which is stored only when electricity is present, and non-volatile memory, which is stored even when there is no power. In general, both volatile and non-volatile memories are used for storing data in an automotive electronic system.

EEPROM is an abbreviation of electrically erasable programmable read only memory. Read only memory (ROM) means that data can only be read. The CD-ROM is a typical read-only memory that can be read only. However, EEPROM can be edited using the professional scanners.
EEPROM storage is mostly used in automobiles. It is common to modify this EEPROM when tuning a car. But you have to edit it very carefully.
