摘要： Examples include a system comprising a processing resource and a memory resource. Examples include a cryptography engine arranged in-line with the processing resource and the memory resource. The cryptography engine is to selectively decrypt data during read accesses of the memory resource by the processing resource.

摘要： In some examples, securing data on a computing device includes one or more cryptographic operations on at least a portion of data stored in a memory module of the computing device in response to a change of operational state of the system from a first operational state to a second operational state.

摘要： Examples associated with persistent memory updating are described. One example includes receiving a first store instruction associated with a first page of memory in a persistent memory from an application. The first page is copied to a new page of the persistent memory. A virtual address space of the application is updated to a location of the new page in a read-write mode. The first store instruction is executed on the new page. A file mapping in the persistent memory is updated from a location of the first page to the location of the new page, and the virtual address space for the location of the new page is updated to a read-only mode.
