Working Principles

The CAT24C64YI-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 and written to or read from using the I2C protocol. When data is written, an electrical charge is applied to specific memory cells, altering their state. This altered state represents the stored information, which can be retrieved by reading the memory cells.
