Abstract

Disclosed herein is a device that includes: a memory cell array including a plurality of memory cells, the memory cell array operates on a first internal voltage; a peripheral circuit accessing selected one or ones of the memory cells, the peripheral circuit operates on a second internal voltage; a first internal voltage generation circuit that supplies the first internal voltage to the memory cell array; and a second internal voltage generation circuit that supplies the second internal voltage to the peripheral circuit. The second internal voltage generation circuit sets the second internal voltage to a first voltage value in a first mode, and to a second voltage value that is different from the first voltage value in a second mode. The first internal voltage generation circuit sets the first internal voltage to a third voltage value in both the first and second modes.
