A word-line test control circuit is provided to test read and write operation, by performing a precharge command after an active command during multi word line test. A burn-in test control unit(110) outputs a test enable signal by performing logic operation of a burn-in test signal. A precharging control unit(400) outputs a row decoder control signal by performing logic operation of the test enable signal, a bank active signal and a multi word line test signal. A row decoder control unit(200) enables or disables a word line off signal according to the row decoder control signal.
