    Abstract: The apparatuses and methods described herein may operate to measure a voltage difference between a selected access line and a selected sense line associated with a selected cell of a plurality of memory cells of a memory array. The voltage difference may be compared with a reference voltage specified for a memory operation. A selection voltage(s) applied to the selected cell for the memory operation may be adjusted responsive to the comparison, such as to dynamically compensate for parasitic voltage drop.

    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.

    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: An array of vertically stacked tiers of memory cells includes horizontally oriented access lines within individual tiers of memory cells and horizontally oriented global sense lines elevationally outward of the tiers. Select transistors are elevationally inward of the tiers. Pairs of local first and second vertical lines extends through the tiers. One vertical line within individual of the pairs is in conductive connection with one of the global sense lines and in conductive connection with one of the two source/drain regions of one of the select transistors. The second vertical line within individual of the pairs is in conductive connection with another of the two source/drain regions of the one select transistor. Individual of the memory cells include a crossing one of the local second vertical lines and one of the horizontal access lines and programmable material there-between. Other aspects including methods, are disclosed.
