Working Principles

The AT24C64A-10TI-2.7 utilizes electrically erasable programmable read-only memory (EEPROM) technology. It consists of an array of floating-gate transistors that can be electrically programmed and erased. Data is stored by charging or discharging the floating gates, which alters the threshold voltage of the transistors. This threshold voltage is then used to determine the logic state of each memory cell.
