Working Principles

The AT24C64C-TH-T utilizes electrically erasable programmable read-only memory (EEPROM) technology. It consists of a grid of memory cells that can be individually programmed or erased using electrical signals. Data is stored by charging or discharging the floating gate within each memory cell, representing binary values.

During read operations, the stored charge in each memory cell is measured, allowing the retrieval of the stored data. Write operations involve applying specific voltage levels to program or erase the memory cells.
