Abstract
A memory device includes a memory array structure having a plurality of memory banks, each memory bank including a plurality of memory groups, each memory group having at least one memory block; and a peripheral structure stacked with the memory array structure in a vertical direction, and having a plurality of memory-group-driver circuits each corresponding to one of the plurality of memory groups, respectively, wherein each memory-group-driver circuit is coupled with word lines of at least one memory block of a corresponding one of memory groups, and overlaps with one of the at least one memory blocks in the vertical direction. Each memory-group-driver circuit may include a precharge-voltage-driver circuit configured to provide a precharge voltage to the word lines, and a discharge-voltage-driver circuit configured to provide a discharge voltage to the word lines.
