Apparatuses, methods, and systems for matrix formation for performing computational operations in memory are included. An embodiment includes a memory having a plurality of levels, wherein each of the plurality of levels includes a plurality of memory cells, voltage circuitry configured to apply sub-threshold voltages to the memory cells of each respective level, a plurality of sense lines, sense circuitry coupled to the plurality of sense lines, wherein the sense circuitry coupled to each respective sense line is configured to sense a state for each of the number of memory cells coupled to that respective sense line responsive to the voltage circuitry applying the sub-threshold voltages to the memory cells of each respective level, and processing circuitry configured to utilize the states for each of the memory cells to form a matrix and perform computational operations on data stored in the memory using the matrix.

Matrix formation for performing computational operations in memory

Methods, systems, and devices for techniques for parallel memory cell access are described. A memory device may include multiple tiers of memory cells. During a first duration, a first voltage may be applied to a set of word lines coupled with a tier of memory cells to threshold one or more memory cells included in a first subset of memory cells of the tier. During a second duration, a second voltage may be applied to the set of word lines to write a first logic state to the one or more memory cells of the first subset and to threshold one or more memory cells included in a second subset of memory cells of the tier. During a third duration, a third voltage may be applied to the set of word lines to write a second logic state to the one or more memory cells of the second subset.
