Working Principles

The AT28C64E-15SC utilizes EEPROM technology, which allows for electrically erasing and reprogramming data. It consists of a grid of memory cells that can be individually addressed and manipulated. When data is written, an electrical charge is applied to the specific memory cell, altering its state. This altered state represents the stored data. During read operations, the stored data is retrieved by sensing the electrical state of each memory cell.
