Abstract:
A ferroelectric tunnel junction unit, a manufacturing method of a ferroelectric film thereof, a memory element, and a method of reading and writing the memory element are disclosed. The ferroelectric tunnel junction unit includes: a first electrode, a second electrode and a ferroelectric film sandwiched between the first and the second electrodes. The ferroelectric film includes at least a base substance and a number of dopants, the base substance including two oxides. Each oxide is at least one of an alkaline earth metal oxide and a transition metal oxide. The dopants include aluminum, silicon, titanium, tantalum, nitrogen, lanthanum, tantalum nitride, titanium nitride, or any combination thereof. By doping different dopants into the base substance of the ferroelectric film and adjusting the doping concentration of the dopants, a coercive electric field of the ferroelectric film may be tuned.

Claim (Index 3):
The ferroelectric tunnel junction unit according to  claim 2 , wherein a general formula of the base substance is HfxZr(1-x)Oy, x ranges between 0.25 and 0.75, and y ranges between 1.8 and 2.2.
