APPARATUS FOR WORDLINE DRIVING IN MEMORY

摘要

PURPOSE: A word line driving device in a memory reduces power consumption at a booster voltage generating circuit by minimizing the use of a boost voltage. CONSTITUTION: A boost high voltage generating unit (130) generates a boost high voltage. A boost low voltage generating unit (140) generates a boost low voltage. A voltage selection unit (210) selects and outputs the boost low voltage in an active state and selects and outputs a low voltage in a stand-by state. A word line driving unit (120) drives a word line of a memory cell by outputting the boost low voltage as a driving voltage in the active state and deactivates the word line of the memory cell by outputting the boost high voltage in the stand-by state.
