Working Principles

The PC28F640J3F75A flash memory utilizes a floating-gate transistor structure to store data. When programming, electrons are trapped in the floating gate, altering the transistor's threshold voltage and storing a logical "1." Erasing is achieved by removing the trapped electrons, resetting the transistor to a logical "0." The stored data can be read by sensing the threshold voltage of each memory cell.
