Working Principles

The 24AA512T-I/SN utilizes EEPROM technology to store data. It consists of an array of floating-gate transistors that can be electrically programmed and erased. When data is written, charges are trapped in the floating gate, altering the transistor's threshold voltage. This change allows the stored data to be retained even when power is removed. Reading the data involves sensing the transistor's threshold voltage and converting it back into digital information.
