Working Principles

The AT49F2048A-70RI utilizes flash memory technology to store data. It consists of a grid of memory cells that can be electrically programmed and erased. When data is written, an electrical charge is applied to the memory cell, altering its state. To erase data, the memory cells are exposed to an intense ultraviolet light source. The device's control pins (CE#, OE#, WE#) enable the user to perform read, write, and erase operations.
