    Abstract: A method for managing data stored in a content addressable memory (CAM) device includes at least the following steps: performing a partial write operation to overwrite only a portion of original write data stored in an entry of the CAM device, and storing updated write data in the entry; and updating a parity flag by a first value to indicate that parity data corresponding to the entry of the CAM device is invalid. Besides, a CAM system employing the method has a CAM device, a storage device and a parity flag controller.

    Abstract translation: 用于管理存储在内容可寻址存储器(CAM)设备中的数据的方法至少包括以下步骤:执行部分写入操作以仅覆盖存储在CAM设备的条目中的原始写入数据的一部分,并且存储更新的写入数据 在入场; 以及将奇偶校验标志更新为第一值以指示与CAM设备的条目相对应的奇偶校验数据无效。 此外,采用该方法的CAM系统具有CAM设备,存储设备和奇偶校验标志控制器。
