Working Principles

The AT24C256W-10SU-2.7 utilizes an I2C-compatible interface for communication with the host device. It employs a combination of electrically controlled transistors and floating gate technology to store and retrieve digital information. When data needs to be written, the chip applies a high voltage to the selected memory cells, causing electrons to tunnel onto or off the floating gate. This process alters the threshold voltage of the transistor, allowing the stored data to be read accurately.
