Abstract

Persistent caching of memory-side cache content for devices, systems, and methods are disclosed and discussed. In a system including both a volatile memory (VM) and a nonvolatile memory (NVM), both mapped to the system address space, software applications directly access the NVM, and a portion of the VM is used as a memory-side cache (MSC) for the NVM. When power is lost, at least a portion of the MSC cache contents is copied to a storage region in the NVM, which is restored to the MSC upon system reboot.
