Integrated circuit with associated memory function

Abstract

A search payload data shift part has n latch parts LT 1 to LTn (n≧2), each of which can store 1-byte latch data, and obtains search payload data having an n-byte length, while shifting payload data inputted from an input terminal, in synchronization with a clock provided from the exterior. Data related to the search payload data is given to a CAM array, as search object data. When the search object data matches entry data of the CAM array, a hit signal ‘hit’ indicating a match is outputted from the CAM array.

1 - 4 . (canceled)  
     
     
         5 . An integrated circuit with associated memory function comprising: 
 an associated memory part capable of storing input data as entry data having a predetermined length;    a checksum operation part for splitting said entry data into a plurality of split data and obtaining checksum operation results of said plurality of split data; and    a selector capable of selectively outputting either of said entry data and said checksum operation results.    
     
     
         6 . The integrated circuit with associated memory function according to  claim 5 , wherein 
 said associated memory part includes a plurality of partial associated memory parts,    said checksum operation part includes a plurality of partial checksum operation parts corresponding to said plurality of partial associated memory parts, said plurality of partial checksum operation parts outputting a plurality of partial checksum operation results, and    said checksum operation results contain an aggregate of said plurality of partial checksum operation results.
