Patent Number: 6,487,133

Title: Semiconductor device

Abstract: The present invention relates to overdrive circuits for generating an operational potential of a sense amplifier. For example, a switch circuit is used to connect a drive node of the sense amplifier with a overdrive potential generation circuit for generating an overdrive potential to be applied to bit lines. A restoration potential generation circuit comprises a push-pull regulator circuit for generating a restoration potential to be applied to bit lines. Consequently, the restoration potential generation circuit can directly connect with the sense amplifier's drive node.
