Abstract: Applications may request persistent storage in nonvolatile memory. The persistent storage is maintained across power events and application instantiations. Persistent storage may be maintained by systems with or without memory management units.

Abstract: Subject matter disclosed herein relates to management of a memory device.

Abstract: Systems and methods relating to pinning selected data to sectors in non-volatile memory. A graphical user interface allows a user to specify certain data (e.g., directories or files) to be pinned. A list of pinned sectors can be stored so that a driver or controller that operates on a sector basis and not a file or directory basis can identify data to be pinned.

Abstract: A memory profiling system profiles memory objects in various memory devices and identifies memory objects as candidates to be moved to a more efficient memory device. Memory object profiles include historical read frequency, write frequency, and execution frequency. The memory object profile is compared to parameters describing read and write performance of memory types to determine candidate memory types for relocating memory objects. Memory objects with high execution frequency may be given preference when relocating to higher performance memory devices.

Abstract: Methods and systems provide memory handling for memory systems with mixed volatile and nonvolatile memory types. In various embodiments, the method or system maintains a page table that marks memory pages in nonvolatile memory as write-protected. When a write is attempted to a write-protected page in nonvolatile memory, a fault is generated. In response to the fault, memory contents of the write-protected nonvolatile page are moved to a page location in a volatile memory.
