Abstract
A semiconductor memory device that can minimize the area of a circuit for generating a BLEQ signal by using one power source voltage terminal floated for the generation of a BLEQ signal. The semiconductor memory device includes a power source supplier configured to supply a power source of a main power source voltage terminal to a sub-power source voltage terminal in response to a mat selection signal for selecting a corresponding memory cell mat among a plurality of memory cell mats, a bit line equalization (BLEQ) signal generator configured to be coupled with the sub-power source voltage terminal and generate a BLEQ signal corresponding to a voltage level of the sub-power source voltage terminal in response to a BLEQ control signal, and a bit line equalizer configured to precharge and equalize a bit line pair in response to the BLEQ signal.
