ABSTRACT:
A sense amplifier is driven by two sense amplifier drivers which operate at a different timing from each other. This can prevent the increase of the peak value of an instantaneous current in the operation of the plurality of differential amplifiers, thus resulting in ensuring that the potential of the signal line connected to the sense amplifier will be changed in a rapid manner. This may bring about a solution of the problem of the delay in timing of starting of specific differential amplifiers so as to enable correct data to be transmitted to the next circuit at all times. Furthermore, by connecting the sense amplifier drivers to opposite ends of the restore and drive signal lines, respectively, the wiring resistance of the restore and drive signal lines may be substantially reduced, thereby improving precise high speed data transmission.
