Working Principles

The AT49F002-12JC utilizes CMOS technology to store data in non-volatile memory cells. It employs a combination of floating gate and tunnel oxide technologies to achieve reliable data storage. When data is written, charges are trapped in the floating gate, altering the threshold voltage of the memory cell. These charges can be erased by applying a high voltage, allowing the cell to be rewritten.
