.. _CIM-PhysicalMemory-ModuleProductID:

``uint16`` **ModuleProductID**

    The Module Product ID is the identifier of the memory device, which is assigned by the manufacturer of the memory device. This field shall be set to the value of the SPD Module Product Identifier. A value of 0000h indicates the Module Product ID is unknown.

    Note that the location (byte addresses) of the SPD Module Product Identifier may vary and is defined by the memory type/technology SPD Standard. For example, for NVDIMM-N DDR4, this field will have the first byte corresponds to the value in byte 192 and the second byte corresponds to the value in byte 193.

For example, for NVDIMM-N DDR4, this field will have the first byte corresponds to the value in byte 320 and the second byte corresponds to the value in byte 321.

    
.. _CIM-PhysicalMemory-MemorySubsystemControllerProductID:

``uint16`` **MemorySubsystemControllerProductID**

    The Memory Subsystem Controller Product ID is the identifier of the memory subsystem controller, which is assigned by the vendor of the memory subsystem controller. This field shall be set to the value of the SPD Memory Subsystem Controller Product Identifier. A value of 0000h indicates the Memory Subsystem Controller Product ID is unknown.

    Note that the location (byte addresses) of the SPD Memory Subsystem Controller Product Identifier may vary and is defined by the memory type/technology SPD Standard. For example, for NVDIMM-N DDR4, this field will have the first byte corresponds to the value in byte 196 and the second byte corresponds to the value in byte 197.

    
.. _CIM-PhysicalMemory-Speed:

``uint32`` **Speed**

    The speed of the PhysicalMemory, in nanoseconds.

    
.. _CIM-PhysicalMemory-Capability-ByteAccessiblePersistentMemory:

``boolean`` **Capability_ByteAccessiblePersistentMemory**

    Is this memory device capabale of supporting "Byte Accessible Persistent Memory" memory operating mode?
