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.
