1. A memory system controller, comprising:

  • one or more sockets for accommodating NVDIMM cards;

    a PCIe interface for coupling the memory system controller to a host;

    a controller coupled to the PCIe interface over a PCIe-compliant connection and to the one or more sockets over respective DDR2 connections, said controller configured to;

    manage data transfers between the host system and a specified one of the NVDIMM sockets in which an NVDIMM card is accommodated as direct memory access (DMA) reads and writes,format data received from the PCIe interface for transmission to the specified NVDIMM socket over the corresponding one or more DDR2 interfaces, andinitiate save and restore operations on the NVDIMM card accommodated within the specified NVDIMM socket in response to power failure and power restoration indications; and

    power detection logic coupled to the PCIe interface and the controller and configured to detect and provide the controller with said power failure and power restoration indications.
