Abstract
An apparatus and method are described for store durability and ordering in a persistent memory architecture. For example, one embodiment of a method comprises: performing at least one store operation to one or more addresses identifying at least one persistent memory device, the store operations causing one or more memory controllers to store data in the at least one persistent memory device; sending a request message to the one or more memory controllers instructing the memory controllers to confirm that the store operations are successfully committed to the at least one persistent memory device; ensuring at the one or more memory controllers that at least all pending store operations received at the time of the request message will be committed to the persistent memory device; and sending a response message from the one or more memory controllers indicating that the store operations are successfully committed to the persistent memory device.
