Abstract

Methods, systems, and devices for voltage equalization for pillars of a memory array are described. In some examples, a memory array may be configured with conductive pillars that are each coupled with a respective set of memory cells, and may be selectively coupled with an access line. To support a dissipation or equalization of charge from unselected pillars, the memory array may be configured with a material layer or level that provides a dissipative coupling, such as a coupling having a relatively high resistance or a degree of capacitance, with a ground voltage or other voltage source (e.g., to support a passive equalization). Additionally, or alternatively, a memory array may be configured to support an active dissipation of accumulated charge or voltage by selectively coupling pillars that have been operated in a floating condition with a ground voltage or other voltage source (e.g., to perform a dynamic equalization).
