CIM_PhysicalMemory¶
Subclass of CIM_Chip
PhysicalMemory is a subclass of CIM_Chip, representing low level memory devices - SIMMS, DIMMs, raw memory chips, etc.
Key properties¶
Local properties¶
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.
uint64
Capacity
The total capacity of this PhysicalMemory, in bytes.
uint32
InterleavePosition
The position of this PhysicalMemory in an interleave. 0 indicates non-interleaved. 1 indicates the first position, 2 the second position and so on. For example, in a 2:1 interleave, a value of ‘1’ would indicate that the Memory is in the ‘even’ position.
boolean
Capability_VolatileMemory
Is this memory device capabale of supporting “Volatile Memory” memory operating mode?
uint32
MaxMemorySpeed
The maximum speed (in MHz) of PhysicalMemory.
string
BankLabel
A string identifying the physically labeled bank where the Memory is located - for example, ‘Bank 0’ or ‘Bank A’.
boolean
Capability_BlockAccessiblePersistentMemory
Is this memory device capabale of supporting “Block Accessible Persistent Memory” memory operating mode?
boolean
IsSpeedInMhz
The IsSpeedInMHz property is used to indicate if the Speed property or the MaxMemorySpeed contains the value of the memory speed. A value of TRUE shall indicate that the speed is represented by the MaxMemorySpeed property. A value of FALSE shall indicate that the speed is represented by the Speed property.
string
FirmwareVersion
Firmware version for this memory device.
uint16
FormFactor
The implementation form factor for the Chip. For example, values such as SIMM (7), TSOP (9) or PGA (10) can be specified.
ValueMap Values 0 Unknown 1 Other 2 SIP 3 DIP 4 ZIP 5 SOJ 6 Proprietary 7 SIMM 8 DIMM 9 TSOP 10 PGA 11 RIMM 12 SODIMM 13 SRIMM 14 SMD 15 SSMP 16 QFP 17 TQFP 18 SOIC 19 LCC 20 PLCC 21 BGA 22 FPBGA 23 LGA
uint16
MemoryTechnology
The memory technology type for this memory device. For example, NVDIMM-N on DDR4.
ValueMap Values 0 Reserved 1 Other 2 Unknown 3 DRAM 4 NVDIMM-N 5 NVDIMM-F 6 NVDIMM-P
uint16
MemoryType
The type of PhysicalMemory. Synchronous DRAM is also known as SDRAM Cache DRAM is also known as CDRAM CDRAM is also known as Cache DRAM SDRAM is also known as Synchronous DRAM BRAM is also known as Block RAM
uint16
DataWidth
Data width of the PhysicalMemory, in bits. A data width of 0 and a TotalWidth of 8 would indicate that the Memory is solely used to provide error correction bits.
uint16
TotalWidth
Total width, in bits, of the PhysicalMemory, including check or error correction bits. If there are no error correction bits, the value in this property should match that specified for DataWidth.
uint32
ConfiguredMemoryClockSpeed
The configured clock speed (in MHz) of PhysicalMemory.
uint32
PositionInRow
Specifies the position of the PhysicalMemory in a ‘row’. For example, if it takes two 8-bit memory devices to form a 16- bit row, then a value of ‘2’means that this Memory is the second device. 0 is an invalid value for this property.
uint16
MemorySubsystemControllerManufacturerID
The Memory Subsystem Controller Manufacturer ID indicates the vendor of the memory subsystem controller. This field shall be set to the value of the SPD Memory Subsystem Controller Manufacturer ID Code. Refer to JEDEC Standard JEP106AU for the list of manufacturer IDs. A value of 0000h indicates the Memory Subsystem Controller Manufacturer ID is unknown.
Note that the location (byte addresses) of the SPD Memory Subsystem Controller Manufacturer ID Code 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 194 and the second byte corresponds to the value in byte 195.
uint16
ModuleManufacturerID
The Module Manufacturer ID indicates the manufacturer of the memory device. This field shall be set to the value of the SPD Module Manufacturer ID Code. Refer to JEDEC Standard JEP106AU for the list of manufacturer IDs. A value of 0000h indicates the Module Manufacture ID is unknown.
Note that the location (byte addresses) of the SPD Module Manufacturer ID Code 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 320 and the second byte corresponds to the value in byte 321.
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.
uint32
Speed
The speed of the PhysicalMemory, in nanoseconds.
boolean
Capability_ByteAccessiblePersistentMemory
Is this memory device capabale of supporting “Byte Accessible Persistent Memory” memory operating mode?
