ABSTRACT:
The present invention provides a sense amplifier driver circuitry connected to a power voltage supply line supplying a power voltage and also connected to a driving voltage supply line supplying a driving voltage. The driver circuitry comprises: a first circuit having a first input terminal receiving at least a first reference voltage and a second input terminal connected to the driving voltage supply line for feeding the driving voltage back to the second input terminal for comparing the driving voltage with the reference voltage, and the first circuit having an output terminal for outputting an output voltage which accords to a difference in potential between the driving voltage and the reference voltage; a switching device connected between the power voltage supply line and driving voltage supply line, the switching device having a control terminal connected to the output terminal of the first circuit for receiving the output voltage so that the switching device performs ON-OFF switching operations in accordance with the output voltage; and a high speed driving device connected to the control terminal of the switching device for turning the switching device ON at a higher speed than when the switching device turns ON in accordance with the output voltage from the first circuit.
