    摘要: A method for reading a nondestructive readout type ferroelectric memory device including a process in which 1-bit data is written in a pair of a cell for storage and a cell for reference disposed in series in the ferroelectric memory device, and a process in which a response obtained when a pulse is impressed to the 1-bit data written in the pair of a cell for storage and a cell for reference is resonated by a resonant circuit with a specified resonance frequency provided at a readout side to thereby output an output signal to be nondestructively readout.
