Abstract
A main control circuit generates a plurality of main control signals of different phases to local control circuits. The local control circuits produce row-related control signals greater in number than the main control signals in accordance with these main control signals. A semiconductor memory device can be easily adapted to change in bank structure, and can perform a fast and stable operation with a low current consumption.
