摘要
Content Addressable Memory (CAM) search operations are aborted in response to a search abort signal, thus preserving previous CAM search results. In one embodiment, a CAM search operation is aborted by activating a local CAM match line in response to a search field provided to a CAM and preventing activation of a global CAM match line associated with the local CAM match line in response to a search abort signal. By preventing activation of global CAM match lines, monotonic storage devices included in a holding register that captures CAM search results are prevented from overwriting previously stored CAM search results.
