Abstract:
A sub word line driving circuit comprising:a first word line driving and clearing means for driving and clearing a first word line by applying according to a first word line driving signal a word line boosting voltage or a ground voltage into the first word line;a first word line potential emitting means for rapidly emitting according to a word line boosting bar voltage an electric potential of the first word line into the ground voltage;a second word line driving and clearing means for driving and clearing a second word line by applying according to a second word line driving signal a word line boosting voltage or a ground voltage into the second word line;a second word line potential emitting means for rapidly emitting according to the word line boosting bar voltage an electric potential of the second word line into the ground voltage; andan equalizing means for equalizing according to the word line boosting bar voltage the first word line and the second word line.
