ABSTRACT:
A sense amplifier and a driving method is described for resolving a flip failure occurrence where the voltage applied across the bit line is within an acceptable threshold range when the data is delivered to the data bus. The driving method includes disconnecting a bit line from a sense amplifying circuit according to a bit line select control signal after performing a read operation according to a read request. Then, connecting the sense amplifying circuit to a data bus according to a column select control signal after the bit line is disconnected from the sense amplifying circuit and deactivating an output terminal of the sense amplifier circuit that is disconnected from the bit line and connected to the data bus during a restore section synchronized to a command following the read command. Finally, delivering the data on the bit line to the output terminal of the sense amplifying circuit to update the output terminal of the sense amplifying circuit by connecting the sense amplifying circuit to to the bit line according to the bit line select control signal.
