Working Principles

The AT24C1024BW-SH25-B utilizes an electrically erasable programmable read-only memory (EEPROM) technology. It stores data using a grid of floating-gate transistors that can be electrically programmed and erased. The memory cells are organized into a matrix, with each cell capable of storing one bit of information. Data is written to the memory by applying appropriate voltage levels to the control pins, and it can be read back by sensing the electrical state of the memory cells.
