Working Principles

M24256-DFDW6TP utilizes electrically controlled floating gate transistors to store and retrieve data. When programming, an electric charge is applied to the floating gate, altering its electrical characteristics. This charge can be removed during erasure, allowing the transistor to return to its original state. The stored charge determines the logic state of each memory cell, representing either a "0" or a "1".
