Abstract: A circuit includes a first driver to provide a first driver signal at an output. The first driver signal corresponds to a voltage operatively coupled to a VSS terminal of the first driver when driving a logic low. A first capacitor includes a first terminal coupled to the VSS terminal of the first driver. A boost circuit includes a first input coupled to the output of the first driver and a first output coupled to a second terminal of the first capacitor. The boost circuit is configured to cause the first capacitor to provide a boosted voltage at the VSS terminal.

Abstract: The present invention provides a method and apparatus for allowing autonomous, way specific tag updates. More specifically, the invention provides way specific tag and status updates while concurrently allowing reads of the ways not currently being updated. If a read hit is determined, then the read is processed in a typical fashion. However, if the read is a read miss and one of the ways is flagged as being updated, then all ways are read again once the specific way has completed its updated.
