1. A method of operation of a computing system comprising:

  • in a non-volatile dual in-line memory module (NVDIMM) having a non-volatile device, a volatile memory device with data, and a non-volatile controller unit, detecting a disruptive volatile memory event by receiving a snoop signal sent to a memory unit controller of the non-volatile controller unit for indicating a memory control signal error, the NVDIMM autonomously configuring the volatile memory device into a refresh mode based on the snoop signal, the memory control signal error triggered based on a state of a connection to the volatile memory device;

    powering the NVDIMM using a backup power unit within the NVDIMM;

    copying the data of the volatile memory device, synchronously, to the non-volatile device based on the disruptive volatile memory event, the data copied without any intervention from outside the NVDIMM; and

    restoring the data, based on an in-band command received by the NVDIMM, to restore the data of the volatile memory device from the non-volatile device without any intervention from outside the NVDIMM.
