Content search extension architecture for programmable intelligent search memory

Abstract

An integrated circuit chip is disclosed that comprises a programmable intelligent search memory (PRISM) for content search.

What is claimed is: 
     
         1 . A dynamic random access memory (DRAM) chip comprising programmable intelligent search memory for content search, said programmable intelligent search memory comprising:
 a. first memory circuits comprising first memory elements to store first group of symbols to form first rule group;   b. second memory circuits comprising second memory elements to store second group of symbols to form second rule group; and   c. third memory circuits comprising rule group transition logic coupled to the first memory circuits and the second memory circuits to enable transition from the first rule group to the second rule group when a rule in the first rule group is evaluated to match the content being examined.   
     
     
         2 . A dynamic random access memory (DRAM) comprising a programmable memory comprising engine to process content; said programmable memory integrated within a bank of the DRAM. 
     
     
         3 . A dynamic random access memory (DRAM) comprising a plurality of programmable memory comprising engine to process content; said programmable memory integrated within plurality of banks of the DRAM; said DRAM further comprising interface between said plurality of programmable memory to communicate configuration and results of processing the content.
