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.

Abstract: Provided is a method of controlling voltage levels of overall outputs in a combinational mode, in an ultrasonic diagnosis apparatus that may operate in the combinational mode. A judging unit of the ultrasonic diagnosis apparatus may judge whether at least a part of individual modes included in the combinational mode exceeds a threshold determined by safety standards, in accordance with an inputted overall output voltage level control command. When it is judged that at least the part of the individual modes exceeds the threshold determined by the safety standards, an output control unit may maintain an individual output with respect to the at least the part, among the voltage levels that may be outputted from a transducer, to be below the threshold, so that the individual output may be below the standards in accordance with the overall output control command.
