## Class Properties

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
BankLabel | string |
Description | string | A string identifying the physically labeled bank where the Memory is located - for example, 'Bank 0' or 'Bank A'.
MappingStrings | string | MIF.DMTF|Memory Device|005.4
MaxLen | uint32 | 64
Capacity | uint64 |
Description | string | The total capacity of this PhysicalMemory, in bytes.
MappingStrings | string | MIF.DMTF|Memory Device|005.5
Units | string | Bytes
ConfiguredMemoryClockSpeed | uint32 |
Description | string | The configured clock speed (in MHz) of PhysicalMemory.
Units | string | MegaHertz
DataWidth | uint16 |
Description | string | 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.
MappingStrings | string | MIF.DMTF|Memory Device|005.8
Units | string | Bits
FormFactor | uint16 |
Description | string | The implementation form factor for the Chip. For example, values such as SIMM (7), TSOP (9) or PGA (10) can be specified.
MappingStrings | string | MIF.DMTF|Memory Device|005.6
Override | string | FormFactor
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23
Values | string | Unknown, Other, SIP, DIP, ZIP, SOJ, Proprietary, SIMM, DIMM, TSOP, PGA, RIMM, SODIMM, SRIMM, SMD, SSMP, QFP, TQFP, SOIC, LCC, PLCC, BGA, FPBGA, LGA
InterleavePosition | uint32 |
Description | string | 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.
MappingStrings | string | MIF.DMTF|Memory Device Mapped Addresses|001.7
IsSpeedInMhz | boolean | false
Description | string | 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.
ModelCorrespondence | string | CIM_PhysicalMemory.Speed, CIM_PhysicalMemory.MaxMemorySpeed
MaxMemorySpeed | uint32 |
Description | string | The maximum speed (in MHz) of PhysicalMemory.
ModelCorrespondence | string | CIM_PhysicalMemory.Speed, CIM_PhysicalMemory.IsSpeedInMHz
Units | string | MegaHertz
MemoryType | uint16 |
Description | string | 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
MappingStrings | string | MIF.DMTF|Memory Device|005.9
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27..32567, 32568..65535

PositionInRow | uint32 |
Description | string | 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.
MappingStrings | string | MIF.DMTF|Memory Device Mapped Addresses|001.6
Speed | uint32 |
Description | string | The speed of the PhysicalMemory, in nanoseconds.
MappingStrings | string | MIF.DMTF|Memory Device|005.24
ModelCorrespondence | string | CIM_PhysicalMemory.MaxMemorySpeed, CIM_PhysicalMemory.IsSpeedInMHz
Units | string | NanoSeconds
TotalWidth | uint16 |
Description | string | 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.
