Working Principles

AT93C46Y1-10YU-1.8-T utilizes an electrically erasable floating-gate transistor technology. The memory cells consist of 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 threshold voltage of each memory cell.
