Working Principles

The AT24C512BY7-YH-T operates based on the principles of electrically erasable programmable read-only memory (EEPROM). It uses floating gate transistors to store and retrieve data. When a write operation is performed, an electrical charge is applied to the floating gate, altering its threshold voltage and storing the desired data. Reading the stored data involves sensing the threshold voltage of the transistor.
