Working Principles

The 24LC1026T-E/SN utilizes an array of floating-gate transistors to store digital information. When programming or erasing data, electrical charges are trapped in or removed from these floating gates, altering their conductivity and representing binary values (0s and 1s). The stored data can be accessed by sending appropriate commands through the I2C interface.
