Abstract:
A non-volatile memory device is disclosed, in which a ballast resistor layer is disposed between the selector element and memory element of a given memory cell of the device. The material composition of the ballast resistor can be customized, as desired, and in some cases may be, for example, a sub-stoichiometric oxide of hafnium oxide (HfO x ), tantalum oxide (TaO x ), or titanium dioxide (TiO x ), or an alloy of any thereof. In accordance with some embodiments, the integrated ballast resistor may serve the function of damping current surge related to the snapback characteristics of the selector element, preserving control of memory element switching. In accordance with some embodiments, an integrated ballast resistor layer provided as described herein may be implemented, for example, in any of a wide range of resistive random-access memory (RRAM) architectures and spin-transfer torque magnetic random-access memory (STTMRAM) architectures, including cross-point implementations of these types of architectures.

Claim (Index 21):
An integrated circuit including a cross-point non-volatile memory device comprising:\n a first plurality of memory cells, each memory cell comprising:\n either a resistive random-access memory (RRAM) element or a spin-transfer torque magnetic random-access memory (STTMRAM) element; \n a threshold selector adjacent the RRAM element or STTMRAM element; and \n a ballast resistor layer between the threshold selector and the RRAM element or STTMRAM element and comprising a sub-stoichiometric oxide of at least one of hafnium oxide (HfO x ), tantalum oxide (TaO x ), titanium dioxide (TiO x ), and an alloy of any thereof; and \n a first electrode layer comprising a first plurality of wires, each wire configured for electronic contact with a corresponding one of the RRAM elements or STTMRAM elements; and a second electrode layer comprising a second plurality of wires, each wire configured for electronic contact with a corresponding one of the threshold selectors.
