ABSTRACT:
An apparatus for supplying current to a semiconductor memory device. A current supply circuit supplies current to an input/output (I/O) drive circuit responsive to a pattern of data input to the I/O drive circuit. The current supply circuit configured to supply current generated by an external voltage to the I/O drive circuit responsive to a first pattern of data input to the I/O drive circuit, and to prevent the current generated by the external voltage from being supplied to the I/O drive circuit responsive to a second pattern of data input to the I/O drive circuit.
