A semiconductor memory apparatus includes a write driver that receives a reset signal, a write enable signal, and a data signal, and transmits data, which is input from the data signal, to an input/output (IO) line when the write enable signal is applied, and an overdrive unit that is connected to the IO line of the write driver and outputs a voltage larger than a driving voltage of the write driver when the write driver outputs a high level.
