PROBLEM TO BE SOLVED: To solve the problem in a ferroelectric memory element that, although many nondestructive readout methods have been studied, each has a problem that the difference between "1" and "0" is small, a problem in the process reliability, and so forth, and they have not been solved, and to provide a nondestructive readout method suitable for a simple matrix structure memory element. SOLUTION: The nondestructive readout type ferroelectric memory includes a step for writing 1 bit information in a pair of a recording cell and a reference cell disposed in series in the ferroelectric memory element and a step for nondestructively reading out an output signal which is outputted by resonating a response when a pulse is applied to the 1 bit information written in the pair of the recording cell and the reference cell at a resonant frequency by a resonance circuit provided to the readout side.
