Working Principles

The M29W640GB70ZS6E flash memory utilizes a floating gate transistor technology. It stores data by trapping electric charge within the floating gate, which alters the transistor's conductive properties. This allows the memory to retain data even when power is removed. The data can be read by applying appropriate voltages to the address and control pins, and programming/erasing operations are performed using specific voltage sequences.
