    Abstract: A method of forming conductive vias comprises forming a first via opening and a second via opening within a substrate. First conductive material of a first conductivity is formed into the first and second via openings. The first conductive material lines sidewalls and a base of the second via opening to less-than-fill the second via opening. Second conductive material is formed into the second via opening over the first conductive material in the second via opening. The second conductive material is of a second conductivity that is greater than the first conductivity. All conductive material within the first via opening forms a first conductive via defining a first maximum conductance elevationally through the first conductive via and all conductive material within the second via opening forms a second conductive via defining a second maximum conductance elevationally through the second conductive via that is greater than said first maximum conductance. Integrated circuit structure comprising conductive vias independent of method of manufacture are disclosed.

    Abstract: Some embodiments include methods of forming electrically conductive contacts. An opening is formed through an insulative material to a conductive structure. A conductive plug is formed within a bottom region of the opening. A spacer is formed to line a lateral periphery of an upper region of the opening, and to leave an inner portion of an upper surface of the plug exposed. A conductive material is formed against the inner portion of the upper surface of the plug. Some embodiments include semiconductor constructions having a conductive plug within an insulative stack and against a copper-containing material. A spacer is over an outer portion of an upper surface of the plug and not directly above an inner portion of the upper surface. A conductive material is over the inner portion of the upper surface of the plug and against an inner lateral surface of the spacer.

    Abstract: Some embodiments include memory arrays. The memory arrays can have global bitlines extending along a first horizontal direction, vertical local bitlines extending perpendicularly from the global bitlines, and wordlines extending along a second horizontal direction which is perpendicular to the first horizontal direction. The global bitlines may be subdivided into a first series at a first elevational level, and a second series at a second elevational level which is different from the first elevational level. The global bitlines of the first series can alternate with the global bitlines of the second series. There can be memory cell material directly between the wordlines and the vertical local bitlines. The memory cell material may form a plurality of memory cells uniquely addressed by wordline/global bitline combinations. Some embodiments include cross-point memory cell units that have areas of about 2F2.
