Working Principles

The AT24C128C-SSHM-T operates based on the principles of EEPROM technology. It utilizes a grid of floating-gate transistors to store digital information. The stored data can be accessed and modified through the I2C interface. When reading data, the chip activates the appropriate memory cells and retrieves the stored information. During the write operation, the chip applies a high voltage to the selected memory cells, allowing electrons to tunnel into or out of the floating gate, altering its charge and thus storing new data.
