Semiconductor integrated circuit device having a constant delay-time circuit for different operating voltages |
摘要 |
The present invention is a method and apparatus for overdriving signals received by a sense amplifier circuit. To this end, an overdrive circuit comprising an n-channel common source switch drives the signal to be sensed for a period of time to a voltage level greater than a normal level. The period of time the signal is overdriven corresponds to the operating voltage of the sense amplifier circuit. Upon completion of the overdriving, a normalization circuit drives the signal to be sensed for a second period of time to the normal level, thereby preparing it for the next memory cycle so that the signals can be once again set to the desired precharge level.
