The row decoder may be configured to select a dummy block and a plurality of sub blocks based on row address signals, a bank select signal, and a dummy delayed bank select signal. The intersection region circuit may delay the bank select signal and may generate a delayed bank select signal and a dummy delayed bank select signal.
