Abstract
An apparatus for pre fetching and restoring data stored in memory cells in a semiconductor memory device includes a bit line sense amplifying unit and a control unit. The bit line sense amplifying unit senses the data stored in the memory cells in response to a bit line sense amplifier driving signal. The control unit drives the bit line sense amplifying unit before data applied on pairs of bit lines are transferred to pairs of data bus lines in response to a control signal during a pre fetching operation. Additionally, the control unit drives the bit line sense amplifying unit after data applied on the pairs of bit lines via the pairs of data bus lines is transferred to the pairs of bit lines in response to the control signal.
