Abstract
A potential level is applied between both electrode of a capacitor so as to polarize a ferroelectric layer sandwiched between the electrodes, and, thereafter, the node between the capacitor and a field effect transistor is caused to enter the floating state so that a large amount of electric charge is induced in the node by virtue of both of the ferroelectric component and the paraelectric component of the capacitor.
