Abstract
A sense amplifier includes an equalization unit configured to precharge a pair of bit lines to a level of a bit line precharge voltage in response to a bit line equalizing signal; and an amplification unit configured to sense and amplify voltages of the pair of bit lines, supply, during an active operation, a ground voltage to a pull-down node of a latch section, and supply, when a precharge signal is enabled, a first voltage lower than the ground voltage to the pull-down node of the latch section for a predetermined time.
