Working Principles

AT29C256-90JI-T utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It stores information in a grid of memory cells that can be individually accessed and modified using electrical signals. The memory cells consist of floating-gate transistors that can trap or release electrons, representing binary data (0s and 1s). By applying specific voltage levels to the control pins, data can be read, written, or erased from the memory.
