An apparatus for controlling a voltage generator of a semiconductor memory is provided to control the operation of the voltage generator accurately according to a bank operation state even if a plurality of banks is enabled or disabled at the same time. A first counter(100) counts the number of memory banks to be enabled. A second counter(200) counts the number of memory banks to be precharged. An enable signal generation unit(300) generates an enable signal to enable a fixed number of voltage generators according to the output of the first counter. A disable signal generation unit(400) generates a disable signal to disable a fixed number of voltage generators according to the output of the second counter. A voltage generator control unit(500-0~500-m) controls a voltage generator connected to itself according to the enable signal, the disable signal and a bank operation command.
