Zusammenfassung: | This application provides a ferroelectric memory and a storage device, to reduce an operating voltage, reduce an interface defect in the ferroelectric memory, and improve durability of the ferroelectric memory. The ferroelectric memory includes at least one storage cell. Each storage cell includes a transistor, a first ferroelectric capacitor, and at least one voltage divider capacitor. The transistor includes a gate electrode, a source electrode, and a drain electrode. One electrode of the first ferroelectric capacitor is connected to the gate electrode. The other electrode of the first ferroelectric capacitor is connected to a word line. One electrode of each voltage divider capacitor in the at least one voltage divider capacitor is connected to the gate electrode, and the other electrode of each voltage divider capacitor in the at least one voltage divider capacitor is connected to the source electrode. |
