Working Principles

The CAT24C164LI-G utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It consists of a grid of memory cells that can be individually addressed for reading or writing operations. When data is written, the memory cells are programmed by trapping charges in a floating gate, which can be later erased by applying electrical signals. This mechanism enables non-volatile data storage.
