A regulator of a bit line precharge voltage and a semiconductor memory device comprising the same are provided to assure precharge time margin by decreasing a bit line precharge voltage level for a certain time by a precharge command. A voltage divider part(100) receives a pulse signal, and divides a core voltage by regulating a resistance value according to the enabling of the pulse signal. A control part(300) generates a pull-up signal and a pull-down signal for controlling a bit line precharge voltage level by receiving the output of the voltage divider part. A driving part(400) drives the bit line precharge voltage as a power supply voltage according to the pull-up signal and the pull-down signal.
