    Abstract: Apparatus might include an array of memory cells and a controller for access of the array of memory cells. The controller might be configured to cause the apparatus to apply a sense voltage level to a control gate of a memory cell of the array of memory cells, generate N determinations whether the memory cell is deemed to activate or deactivate while applying the sense voltage level, wherein N is an integer value greater than or equal to three, deem the memory cell to have a threshold voltage in a first range of threshold voltages lower than the sense voltage level in response to a majority of the N determinations indicating activation of the memory cell, and deem the memory cell to have a threshold voltage in a second range of threshold voltages higher than the sense voltage level in response to a majority of the N determinations indicating activation of the memory cell.

    Abstract: Control logic in a memory device initiates a first loop of a program operation, the first loop comprising (a) a program phase where a plurality of memory cells associated with a selected wordline in a block of the memory array are programmed to respective ones of a plurality of programming levels and (b) a corresponding program verify phase. The control logic further identifies memory cells of the plurality of memory cells associated with a first sub-set of the plurality of programming levels to be verified during the program verify phase, the first sub-set comprising two or more dynamically selected programming levels comprising at least a lowest programming level and a second lowest programing level of the respective ones of the plurality of programming levels. The control logic further causes a first program verify voltage to be applied to the selected wordline during the program verify phase, and performs concurrent sensing operations on the identified memory cells of the plurality of memory cells associated with the first sub-set of the plurality programming levels to determine whether the identified memory cells were programmed to respective program verify threshold voltages corresponding to the first sub-set of the plurality of programming levels during the program phase of the first loop of the program operation.

    Abstract: Some embodiments include an apparatus having semiconductor pillars in a substantially hexagonally closest packed arrangement. The hexagonally closest packed arrangement includes a repeating pillar pattern which has at least portions of 7 different pillars. Each of the different pillars in a respective one of the repeating pillar patterns is capable of being electrically coupled to a different data line of a plurality of data lines. Some embodiments include an apparatus having semiconductor pillars in a substantially hexagonally closest packed arrangement. The hexagonally closest packed arrangement includes a repeating pillar pattern having at least portions of 7 different pillars. All 7 different pillars of a repeating pillar pattern are encompassed by a single drain-side select gate (SGD).
