Working Principles

The 24C08B-E/P utilizes an I2C interface to communicate with the host device. It employs a combination of electrically controlled gates and floating gate transistors to store and retrieve data. When writing data, an electrical charge is applied to the floating gate, altering its state. This change in state determines the stored information. During read operations, the stored charge is measured, allowing the retrieval of the desired data.
