ABSTRACT:
A semiconductor memory device comprising a memory cell array including at least two banks and a desired number of voltage pumping circuits each for pumping an input voltage to a desired level. The voltage pumping circuits are driven in response to at least two bank selection control signals. The voltage pumping circuits are arranged in the semiconductor memory device in a proper manner to efficiently perform the voltage pumping operation, so as to increase the pumping efficiency. Further, the proper arrangement of the voltage pumping circuits contributes to the integration of the semiconductor memory device.
