Working Principles

The 24LC64T-E/SN utilizes a combination of electrically erasable and programmable memory cells to store data. When data needs to be written, the chip applies an electrical charge to specific memory cells, altering their state. To erase data, the chip removes the electrical charge from the corresponding memory cells. This process allows for repeated read, write, and erase operations without requiring physical modifications to the chip.
