Abstract: Example implementations may relate to a version controller allocating a copy page in persistent memory upon receiving, from an application executing on a processor, a copy command to version an image page for an atomic transaction. The version controller may receive application data addressed to a cache line of the image page, and may write the application data to a cache line of the copy page corresponding to the addressed cache line of the image page. If the version controller receives a replace-type transaction commit command, the version controller may generate a final page by either forward merging the image page into the copy page or backward merging the copy page into the image page, depending a merge direction policy.

Abstract: According to an example, data may be replicated using a dual-port nonvolatile dual in-line memory module (NVDIMM). A processor may request, through a first port of the dual-port NVDIMM, to store data to universal memory of the dual-port NVDIMM and to commit the data to remote storage according to a high-availability storage capability of the dual-port NVDIMM. The process may then receive a notification from the dual-port NVDIMM that the data has been transparently committed to the remote storage through a second port of the dual-port NVDIMM.

Abstract: A method for restricting write access to a non-volatile memory. The method includes receiving a request to write to a protected location in the non-volatile memory and determining whether the protected location is in a write-protected state. If the protected location is not in a write-protected state, the method includes writing data indicated by the request to the protected location. If the protected location is in a write-protected state, the method includes rejecting the request. The protected location stores a validation key to validate the contents of another portion of the non-volatile memory.
