Abstract
A semiconductor device that initializes memory cells of an activated wordline group is provided. The device includes: a control signal generation circuit, which generates first and second control signals based on an activated setting signal and an initial data value during an initial value setting operation; a first power supply circuit, which supplies power to bitlines in response to the first control signal; a second power supply circuit, which supplies power to complementary bitlines in response to the second control signal; a plurality of wordlines connected to respective memory cells; and a row decoder, which selects a group of wordlines from among the plurality of wordlines based on the setting signal and a selection address and simultaneously activates the selected group of wordlines.
