Abstract: A memory controller circuit is disclosed. The memory controller circuit is coupled to an external memory device. The memory controller circuit selectively generates error-correction information for a user input. The selection is based on whether the user input is one of predefined inputs. In order to facilitate that, the memory controller circuit includes a command processor circuit and a memory circuit. The error-correction information is stored within the memory circuit located within the memory controller circuit. Selectively generating the error-free correction information may significantly reduce the amount of memory storage that is required within the memory controller circuit.

Abstract: Mechanisms for measuring, analyzing, and presenting performance data associated with a memory controller system are described. The mechanisms include a performance monitor that detects and analyzes performance including efficiency and latency of a memory controller system. In addition to determining performance, the systems identifies reasons for loss of memory controller system efficiency. Moreover, the reasons, the efficiency, and the latency are analyzed and presented in a manner easily understandable to a user.
