Abstract: In one embodiment, a system includes a non-volatile memory that may serve as both the main memory system and the backing store (or persistent storage). In some embodiments, the non-volatile memory is divided into a main memory portion and a persistent portion. Data in the main memory operation may be encrypted using one or more first keys, and data in the persistent portion may be encrypted using one or more second keys, in an embodiment. The volatile behavior of main memory may be implemented by discarding the one or more first keys in a power down event or other event that indicates a loss of main memory data, while the one or more second keys may be retained. In one embodiment, the physical address space of the non-volatile memory may be a mapping from a second physical address space that is used within the system.

Abstract: In one embodiment, when a secondary application on an electronic device is selected for deactivation, the memory associated with the application can be gathered, compacted and compressed into a memory freezer file. The memory freezer file can be stored in non-volatile memory with a reduced storage footprint compared to a memory stored in a conventional swap file. When the selected application is to be reactivated, the compressed memory in the memory freezer file can be quickly restored to process memory.

Abstract: In one embodiment, a memory allocator of a memory manager can service memory allocation requests within a specific size-range from a section of pre-reserved virtual memory. The pre-reserved virtual memory allows allocation requests within a specific size range to be allocated in the pre-reserved region, such that the virtual memory address of a memory allocation serviced from the pre-reserved region can indicate elements of metadata associated with the allocations that would otherwise contribute to overhead for the allocation.

Abstract: Multiple variants of a data processing system, which maintains I/O priority from the time a process makes an I/O request until the hardware services that request, will be described. In one embodiment, a data processing system has one or more processors having one or more processor cores, which execute an operating system and one or more applications of the data processing system. The data processing system also can have one or more non-volatile memory device coupled to the one or more processors to store data of the data processing system, and one or more non-volatile memory controller coupled to the one or more processors. The one or more non-volatile memory controller enables a transfer of data to at least one non-volatile memory device, and the priority level assigned by the operating system is maintained throughout the logical data path of the data processing system.

Abstract: A memory management system, such as a virtual memory manager that manages a virtual memory space that includes volatile memory (e.g. DRAM) and non-volatile memory (e.g., flash memory) creates a reserved portion of memory in the volatile memory for at least one user application in one embodiment, and that reserved portion can also store content that it restricted to read only permission within the non-volatile memory.

Abstract: A method and an apparatus for a memory device including a dynamically updated portion of compressed memory for a virtual memory are described. The memory device can include an uncompressed portion of memory separate from the compressed portion of memory. The virtual memory may be capable of mapping a memory address to the compressed portion of memory. A memory region allocated in the uncompressed portion of memory can be compressed into the compressed portion of memory. As a result, the memory region can become available (e.g. after being compressed) for future allocation requested in the memory device. The compressed portion of memory may be updated to store the compressed memory region. The compressed memory region may be decompressed back to the uncompressed portion in the memory device in response to a request to access data in the compressed memory region.
