ABSTRACT:
A semiconductor memory device for reducing a precharge time is provided. The semiconductor memory device may include a sense amplifier, a precharge unit and an equalizing circuit. The sense amplifier may sense and amplify a difference between data transmitted through a first bit line and data transmitted through a second bit line in response to a sense amplifier enable signal. The precharge unit may precharge voltage levels of the first bit line and the second bit line to a precharge voltage level in response to a precharge enable signal. The equalizing circuit may be connected to the sense amplifier and the precharge unit and may control the voltage levels of the first bit line and the second bit line to be equal to each other in response to the sense amplifier enable signal. The semiconductor memory device may reduce a time required to perform a precharge operation and/or minimize an increase of the circuit size.
