In the Arduino UNO board, the MCU is an ATMega328P. Such as many other MCU,  it has a FLASH memory, an EEPROM memory and a SRAM.

The Flash memory is the place where your sketch is stored. Its size is 32 KB of which 0.5 KB used by bootloader.

The EEPROM is a like a tiny harddisk, where you can store information or settings that may be retrieved later by another sketch or between resets. Its size is 1KB

In this tutorial you'll learn how read the Arduino UNO EEPROM using Arduino ISP.
