Abstract: A system includes a non-volatile memory to store a page cache that contains pages of data allocated by an operating system, the pages in the page cache being persistent across a power cycle of the system. The page cache is located in a specified region of the non-volatile memory and is to store the pages of data without tagging a memory region.

Abstract: A non-volatile main memory stores state information of at least one program executing in the system, and metadata indicating whether a system is to be resumed to a prior state on a next start. As part of restarting the system from a mode in which power is removed from the system, the system is resumed to the prior state using the state information stored in the non-volatile main memory, in response to the metadata indicating that the system is to be resumed to the prior state.

Abstract: Examples disclosed herein relate to automatic persistent memory management. An example system includes a non-volatile memory to allocate space as persistent data space and a processor executing a program to generate program data to be stored as persistent data in the persistent data space. The example system can also include a memory manager to protect program data that is reachable from persistence roots from deallocation.

Abstract: In one example in accordance with the present disclosure, a method is described. According to the method, during execution of an application as an application asset is called, an asset map that is stored in a persistent memory device is searched for an asset identifier associated with the application asset. Using this asset identifier, an application asset stored in a persistent memory device is located. The persistent memory device is directly accessed by a processor executing the application. A processor the processes the application asset from its location in the persistent memory device.

Abstract: Examples include a system comprising a non-volatile memory and a volatile memory. Examples migrate system memory between the volatile memory and the non-volatile memory. After migration, examples translate virtual addresses to physical memory addresses corresponding to the volatile memory and/or non-volatile memory.

Abstract: In one example, a computer having a processor and a byte-addressable non-volatile read-write main memory. The memory is partitioned into plural regions, each region having at least one defined operational property. At least one of the regions is a metadata region to store plural data sets. Each data set specifies a location in memory, and the at least one operational property, of a corresponding one of the regions.
