ABSTRACT:
A write driver of a semiconductor memory device is disclosed which includes: a data input incorporating a noninverted data input portion and an inverted data input portion for buffering an inputted data signal and an inverted data signal in response to write enable signal; a pulse generator generating a first control pulse signal in response to a state transition of the data signal or inverted data signal and a phase-inverted second control pulse signal of the first control pulse signal in response to an inverted write enable signal; a transmitter for transmitting the inverted and noninverted data which have been buffered to a pair of data lines in response to the first control pulse signal; and a precharger for precharging the pair of data lines in response to the second control pulse signal. In performing a write operation, the write driver precharges the pair of data lines after writing data in the memory cell so that, in performing the subsequent read operation, it can increase the operating speed and reduce noise generated during precharge of the data lines due to the decrease of the voltage swing of the data lines.
