Working Principles

AT25040N-10SC-2.7 utilizes electrically erasable floating-gate technology. The memory cells consist of transistors that can store charge in a floating gate, representing binary data. To write data, an electrical charge is applied to the floating gate, altering its state. Reading data involves sensing the charge level in the floating gate. Erasing data is achieved by removing the charge from the floating gate.
