Abstract
In an embodiment, a memory device includes a stack of tiers of memory cells, a tier of local devices at a level above the stack of tiers of memory cells, and a tier of global devices at substantially a same level as the tier of local devices. A local device may provide selective access to a data line. A global device may provide selective access to a global access line. A tier of memory cells may be selectively coupled to a global access line by the global device of the tier of global devices.
