    • A data processing apparatus has a memory element array (330) having a plurality of entries each formed by a memory element of more than one bit having a data shift function and a data comparison function, and the memory element array is arranged so that data can be shifted between corresponding bit positions of adjacent entries. Further, the data processing apparatus has a priority-judging circuit (340) for identifying one of the entries according to predetermined priorities based on results of comparison between data input to the entries in common and contents held by the memory elements constituting the entries. Even when the data held by an entry located halfway is nullified, data shift between entries can avoid that the entry with nullified data remains halfway, and enables the entries to hold valid data in order with the data densely aligned. The time sequence when data are held can be made coincident with the alignment of entries readily. As the time sequence of the entries is ensured uniquely, a given data can be identified from CAM search results by factoring in the priorities following the time sequence.
