Abstract: An example apparatus includes: a plurality of first regions each including second and third regions; a plurality of main word driver circuits each configured to activate an associated one of a plurality of main word lines responsive to a row address signal; and a voltage control circuit configured to supply a first power voltage to the plurality of main word driver circuits in a first operation mode and a second power voltage different from the first power voltage to the plurality of main word driver circuits in a second operation mode. One or ones of the plurality of main word driver circuits is arranged in the second region included in each of the plurality of first regions. The voltage control circuit is divided into multiple circuit portions arranged in two or more third regions in two or more of the plurality of first regions, respectively.
