The memory array includes first and second ferroelectric memory devices formed along a gate electrode, a channel layer and a ferroelectric layer between the gate electrode and the channel layer. The ferroelectric memory devices include: a common source/drain electrode and two respective source/drain electrodes, separately in contact with a side of the channel layer opposite to the ferroelectric layer, wherein the common source/drain electrode is disposed between the respective source/drain electrodes; and first and second auxiliary gates, capacitively coupled to the channel layer, wherein the first auxiliary gate is located between the common source/drain electrode and one of the respective source/drain electrodes, and the second auxiliary gate is located between the common source/drain electrode and the other respective source/drain electrode.

Abstract: A method for fabricating magnetoresistive random-access memory cells (MRAM) on a substrate is provided. The substrate is formed with a magnetic tunneling junction (MTJ) layer thereon. When the MTJ layer is etched to form the MRAM cells, there may be metal components deposited on a surface of the MRAM cells and between the MRAM cells. The metal components are then removed by chemical reaction. However, the removal of the metal components may form extra substances on the substrate. A further etching process is then performed to remove the extra substances by physical etching.
