Working Principles

The 24LC04B-I/STG uses a floating gate transistor structure to store data. When a byte is written, an electric charge is trapped in the floating gate, altering the threshold voltage of the transistor. This change in threshold voltage represents the stored data. The data can be erased by applying a high voltage to the memory cell, which removes the trapped charge.
