Abstract
A signal sensing circuit and a semiconductor memory device using the same are provided. The signal sensing circuit comprises a sense amplifier, a kick transistor, a first control transistor, a second control transistor, a pre-charge circuit, and a recovery circuit. The kick transistor is used to pull up the operation voltage of the sense amplifier to improve the small signal sensing speed of the sense amplifier. After the signal is sensed, the recovery circuit will pull down the operation voltage of the sense amplifier to the standard level. In the present invention, the small signal sensing speed is greatly improved and the operation voltage of sense amplifier is kept away from the saturated level.
