EEPROM
AT24C04 4-Kbit Serial EEPROM
The AT24C04 provides 4096 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 512 words of 8 bits each.
AT24C256C 256-Kbit I2C EEPROM
The AT24C256 is a 32K byte, 8-pin EEPROM IC. As we know EEPROM stands for Electrically Erasable Programmable Read-Only Memory, we can store information on this IC and it will remain there even when the power is turned off just like your pen drive.
