Pattern-Addressable Memory

Robinson, Ian N.



Abstract: Associative memories, such as those used in caches and translation look-aside buffers, have proven their suitability for dealing with the dynamic and unpredictable aspects of runtime data. Pattern addressable memory extends this capability from simple data words to the complex data structures generated and used by applications at runtime. The PAM chip is a custom associative memory specialized to handle the syntax and associated pattern matching rules common to a range of symbolic processing applications. An array of these chips is used to build an associative coprocessor for a workstation.
