Abstract
In an embodiment, a non-volatile memory device is proposed. The device includes a plurality of local pull-up stages distributed along a group of memory portions in a memory array. Each local pull-up stage includes, for each wordline that extends through the group of memory portions, a corresponding local pull-up transistor of an NMOS type. The local pull-up transistors of each local pull-up are configured to locally decouple the corresponding wordline from a node at a first reference potential in response to a wordline that extends through the group of memory portions being selected, and locally couple the corresponding wordline to the node at the first reference potential in response to all the wordlines that extend through the group of memory portions being deselected to restore locally a deselection voltage on a wordline previously selected.
