Abstract
A sense amplifier of a semiconductor memory device for performing a high-speed sensing operation. A sensing node SAN and SAN of the sense amplifier is precharged to a power voltage level and during a sensing operation, first and second clock signals which are shifted to the power voltage and a ground voltage level, respectively, are applied to the sense amplifier. Thus, a potential difference of the sensing node dependent on a precharge state of the power voltage level is generated quickly and sufficiently. Therefore, the high speed sensing operation and a fast access of data can be performed, thereby improving the performance of the semiconductor memory device.
