Abstract
A voltage generation circuit includes a global driver, a local driver, and a local voltage converter. The global driver changes the voltage level of a second voltage line based on the voltage levels of a first boundary voltage and a first voltage line and changes the voltage level of a fourth voltage line based on the voltage levels of a second boundary voltage and a third voltage line. The local driver adjusts the voltage levels of the first and third voltage lines based on the voltage levels of the second and fourth voltage lines. The local voltage converter generates an internal voltage having a voltage level between the voltage levels of the first and third voltage lines.
