    摘要： Briefly, in accordance with an embodiment of the invention, a method and apparatus to avoid incoherency between a cache memory and a flash memory is provided. The method may include invalidating at least one cache line of information stored in the cache memory to avoid incoherency between the cache memory and the flash memory in response to a flash erase operation, a flash write operation, an operation that makes information inaccessible in the flash memory, or an operation that moves information from one region of the flash memory to another region of the flash memory. Other embodiments are described and claimed.

    摘要： An autonomous memory device in a distributed memory sub-system can receive a database downloaded from a host controller. The autonomous memory device can pass configuration routing information and initiate instructions to disperse portions of the database to neighboring die using an interface that handles inter-die communication. Information is then extracted from the pool of autonomous memory and passed through a host interface to the host controller.

    摘要： A memory profiling system profiles memory objects in volatile memory and identifies memory objects as candidates to be stored and read directly from nonvolatile memory. The profiling system monitors memory accesses via page faults and identifies a memory object to be loaded in volatile memory. The profiling system uses page faults to determine a page fault type and a write frequency for the memory object, and determines the memory object's memory access type. The profiling system determines whether the object's memory access type meets the capabilities of the nonvolatile memory technology. If the memory access type meets the nonvolatile memory technology capabilities, the profiling system identifies the memory object as a candidate to be transitioned to and read directly from nonvolatile memory (e.g., NOR and PCM). The profiling system stores the memory object candidates in nonvolatile memory such that the memory objects are read directly from nonvolatile memory.

    摘要： Described herein are methods for accessing a block-based storage device having a memory-mapped interface and a block interface. In one embodiment, an apparatus (e.g., block-based storage device) includes a storage array to store data and a memory-mapped interface that is coupled to the storage array. The memory-mapped interface includes memory-mapped memory space. The memory-mapped interface receives direct access requests from a host to directly access memory-mapped files. The apparatus also includes a block interface that is coupled to the storage array. The block interface receives block requests from a storage driver to access the storage array.
