Working Principles

The AT24C256-10PU-1.8 operates based on the principles of EEPROM technology. It utilizes a grid of floating-gate transistors to store and retrieve data. When data needs to be written, an electric charge is applied to the floating gate, altering its electrical characteristics. This change in charge allows the transistor to represent either a "0" or a "1" bit. The stored data can be read by applying appropriate voltage levels to the memory cells.
