摘要
Apparatuses and methods for maintaining an active state of a word driver signal are described. The word driver may be included in a memory device including a hierarchical structured main word lines and subword lines. The subword lines may be driven by subword drivers that are activated by main word drivers and word drivers. During an operation such as a refresh operation, a driving signal provided by a word driver to a subword driver may be held in an active state while the driving signal provided by a main word driver to the subword driver transitions between active and inactive states. In some examples, the word driver may include a latch for latching an activation signal at an initiation of a refresh operation to maintain a state of the driving signal.
