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.
