GRACEFUL SHUTDOWN WITH ASYNCHRONOUS DRAM REFRESH OF NON-VOLATILE DUAL IN-LINE MEMORY MODULE

A graceful shutdown of a computer system is initiated by sending a command to an asynchronous dynamic random access memory refresh (ADR) trigger device to assert an ADR trigger. Responsive to the command, the ADR trigger device asserts the ADR trigger to initiate an ADR of a non-volatile dual in-line memory module (NVDIMM) of the computer system. In response to the ADR trigger being asserted by the ADR trigger device, an ADR of the NVDIMM is performed before completing the graceful shutdown of the computer.
