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: 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 apparatus of a device that manages a thermal profile of a device by selectively throttling input/output operations of the device is described. In an exemplary embodiment, the device monitors the thermal profile of the device, where the device executes a plurality of processes that utilize storage of the device. In addition, the plurality of processes include a high priority process and a low priority process. If the thermal profile of the device exceeds a thermal threshold, the device decreases a first bandwidth range for the low priority process and maintains a second bandwidth range for the high priority process. The device further processes a storage request of the low priority process using the first bandwidth range and processing a storage request of the high priority process using the second bandwidth range.

Abstract: A method for resource management of a data processing system is described herein. According to one embodiment, a token is periodically pushed into a memory usage queue, where the token includes a timestamp indicating time entering the memory usage queue. The memory usage queue stores a plurality of memory page identifiers (IDs) identifying a plurality of memory pages currently allocated to a plurality of programs running within the data processing system. In response to a request to reduce memory usage, a token is popped from the memory usage queue. A timestamp of the popped token is then compared with current time to determine whether a memory usage reduction action should be performed.

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: 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.
