A semiconductor memory device and a method of inputting and outputting the data in the semiconductor memory device are provided to reduce the power consumption by performing the precharge and the data masking reset operation in the write termination point of time. A semiconductor memory device(1000) comprises a memory cell array(1100), an input/output path(1200), and a control signal generation circuit(1300). The input/output path performs the input-output line precharge operation and the data masking reset operation in the write termination point of time. The input/output path outputs the data stored in the memory cell array at the read mode. The control signal generation circuit generates the write termination signal corresponding to the write termination point of time in response to the inscribe column selection signal.
