Abstract
Systems and methods relate to a matchline receiver of a content-addressable memory (CAM). A matchline of the CAM, which provides a hit/miss indication for a search operation of a data word is provided to the matchline receiver. The matchline receiver comprises a retention circuit to provide a hit/miss output, wherein the retention circuit retains, at the hit/miss output, the hit/miss indication provided by the matchline during a first clock phase of a clock, even if the hit/miss indication provided by the matchline is modified by a write operation or an invalidation operation during the first clock phase.
