Abstract
A ferroelectric nonvolatile semiconductor memory using a ferroelectric film as a dielectric film between a floating gate and a control gate, wherein a write switching transistor is provided between the floating gate and the bit line so as to enable the application of any voltage to the ferroelectric film using the voltage applied to the control gate and the voltage applied to the bit line and thereby enabling writing by a low voltage.
