ABSTRACT:
Ferroelectric memory cells (3) are presented, in which a cell resistor (R) is integrated into the cell capacitor (C) to inhibit charge accumulation or charge loss at the cell storage node (SN) when the cell (3) is not being accessed while avoiding significant disruption of memory cell access operations. Methods (100, 200) are provided for fabricating ferroelectric memory cells (3) and ferroelectric capacitors (C), in which a parallel resistance (R) is integrated in the capacitor ferroelectric material (20) or in an encapsulation layer (46) formed over the patterned capacitor structure (C).
