    摘要: Method and apparatus to scrub memory is disclosed. A patrol request, for example a read/write request, may be raised to the memory command scheduler in an out of order memory controller to scrub the memory. The patrol read/write request may be raised as and when patrol interval timer expires. The patrol read/write request may also be raised based on presence of a transaction in-flight to the memory, retry response from the memory command scheduler and correctable or non-correctable error response from the memory command scheduler. An interrupt may be raised to a processor upon completion response from the memory command scheduler.

    摘要: A method and apparatus for parallelizing address-mapping and page referencing in a memory controller. The page referencing may apply an input address to two separate content addressable memory components along with masks from a configuration register identifying rank-bank bits, page status bits and non-column bits. The content addressable memories each determine if matching content is present generating a ‘hit’ or ‘miss.’ The hit and miss indicators are applied to combinational logic to determine whether to generate a CAS, RAS-CAS or PRE-RAS-CAS indicator.

    摘要: Techniques and mechanisms for managing a delivery of power to a resource of an input/output (I/O) interface. In an embodiment, a first link of a plurality of communication links is monitored. Of the plurality of links, a first set of resources of the I/O interface is to support communication only via the first link. One or more other resources of the I/O interface are for supporting communications of another link of the plurality of links. In another embodiment, a resource of the first set of resources is decoupled from a power supply in response to detecting a total number of active lanes of the first link, decoupling.
