Working Principles

The AT24C64W-10SI utilizes electrically erasable programmable read-only memory technology. It consists of an array of floating-gate transistors that can be electrically programmed and erased. Data is stored in these transistors as charge levels, which can be read by applying appropriate voltage levels.

During write operations, the chip applies high voltages to the selected memory cells, altering their charge levels to store the desired data. Reading involves applying lower voltages and sensing the resulting charge levels to retrieve the stored information.
