1. A memory system, comprising: a memory controller operable to generate first control signals according to a standard interface, the memory controller further including an attachable behaviors circuit adapted to receive configuration data, the configuration data causing the attachable behaviors circuit to implement corresponding memory behaviors, and the attachable behaviors circuit operable in combination with the memory controller to generate memory addresses using the configuration data, the generated memory addresses defining the corresponding memory behaviors; a memory interface adapter coupled to the memory controller, the memory interface adapter operable responsive to the generated memory addresses to develop control signals adapted to access corresponding data storage locations; and the attachable behaviors circuitry is operable to execute corresponding memory behaviors without executing programming instructions.
