Working Principles

The AT24C1024B-TH-T chip utilizes EEPROM technology, which allows for electrically erasing and programming data. It consists of a grid of memory cells that can be individually addressed for read or write operations. When data is written, an electrical charge is applied to the memory cell, altering its state. This altered state can be read back later. The chip communicates with the host device using the I2C interface.
