A microcontroller might need to store its data like sensor value, or a particular count or image data for a long period of time. The most common type of memory used with the microcontroller based systems is EEPROM. The EEPROM stands for Electrically Erasable Programmable Read Only Memory which is a kind of Read Only Memory (ROM), which can be written and erased by means of electrically programming and hence the name. Once programmed the data it will remain in the memory for a very long time even if there is no power available.
