--- | --- | --- | ---
Name | Data Type | Value
CorrectableError | boolean |
Deprecated | string | CIM_MemoryError.CorrectableError
Description | string | Boolean indicating that the most recent error was correctable. If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.
MappingStrings | string | MIF.DMTF|Physical Memory Array|001.8
EndingAddress | uint64 |
Description | string | The ending address, referenced by an application or operating system and mapped by a memory controller, for this Memory object. The ending address is specified in KBytes.

PUnit | string | byte * 10^3
Units | string | KiloBytes
ErrorAccess | uint16 |
Deprecated | string | CIM_MemoryError.ErrorAccess
Description | string | An integer enumeration indicating the memory access operation that caused the last error. The type of error is described by the ErrorInfo property. If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.
MappingStrings | string | MIF.DMTF|Physical Memory Array|001.10
ValueMap | string | 1, 2, 3, 4, 5
Values | string | Other, Unknown, Read, Write, Partial Write
ErrorAddress | uint64 |
Deprecated | string | CIM_MemoryError.StartingAddress
Description | string | Specifies the address of the last memory error. The type of error is described by the ErrorInfo property. If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.

ErrorDataOrder | uint16 |
Deprecated | string | CIM_MemoryError.ErrorDataOrder
Description | string | The ordering for data stored in the ErrorData property. "Least Significant Byte First" (value=1) or "Most Significant Byte First" (2) can be specified. If ErrorTransferSize is 0, then this property has no meaning.
ValueMap | string | 0, 1, 2
Values | string | Unknown, Least Significant Byte First, Most Significant Byte First
ErrorInfo | uint16 |
Deprecated | string | CIM_MemoryError.ErrorInfo

Description

string

An integer enumeration describing the type of error that occurred most recently. For example, single (value=6) or double bit errors (7) can be specified using this property. The values, 12-14, are undefined in the CIM Schema since in DMI, they mix the semantics of the type of error and whether it was correctable or not. The latter is indicated in the property, CorrectableError.

ValueMap | string | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
Values | string | Other, Unknown, OK, Bad Read, Parity Error, Single-Bit Error, Double-Bit Error, Multi-Bit Error, Nibble Error, Checksum Error, CRC Error, Undefined, Undefined, Undefined
ErrorMethodology | string |
Description | string | ErrorMethodology for Memory is a string property that indicates whether parity or CRC algorithms, ECC or other mechanisms are used. Details on the algorithm can also be supplied.
MappingStrings | string | MIF.DMTF|Physical Memory Array|001.7
Override | string | ErrorMethodology
ErrorResolution | uint64 |
Deprecated | string | CIM_MemoryError.ErrorResolution
Description | string | Specifies the range, in bytes, to which the last error can be resolved. For example, if error addresses are resolved to bit 11 (ie, on a typical page basis), then errors can be resolved to 4K boundaries and this property is set to 4000. If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.
MappingStrings | string | MIF.DMTF|Memory Device|005.21, MIF.DMTF|Physical Memory Array|001.15
PUnit | string | byte
Units | string | Bytes
ErrorTime | datetime |
Deprecated | string | CIM_MemoryError.ErrorTime
Description | string | The time that the last memory error occurred. The type of error is described by the ErrorInfo property. If the Error Info property is equal to 3, "OK", then this property has no meaning.
ErrorTransferSize | uint32 |
Deprecated | string | CIM_MemoryError.ErrorTransferSize
Description | string | The size of the data transfer in bits that caused the last error. 0 indicates no error. If the ErrorInfo property is equal to 3, "OK", then this property should be set to 0.
MappingStrings | string | MIF.DMTF|Physical Memory Array|001.11
PUnit | string | bit
Units | string | Bits
OtherErrorDescription | string |
Deprecated | string | CIM_MemoryError.OtherErrorDescription
Description | string | Free form string providing more information if the Error Type property is set to 1, "Other". If not set to 1, this string has no meaning.
ModelCorrespondence | string | CIM_Memory.ErrorInfo
StartingAddress | uint64 |
Description | string | The beginning address, referenced by an application or operating system and mapped by a memory controller, for this Memory object. The starting address is specified in KBytes.
MappingStrings | string | MIF.DMTF|Memory Array Mapped Addresses|001.3, MIF.DMTF|Memory Device Mapped Addresses|001.4
PUnit | string | byte * 10^3
Units | string | KiloBytes
SystemLevelAddress | boolean |
Deprecated | string | CIM_MemoryError.SystemLevelAddress
Description | string | Boolean indicating whether the address information in the property, ErrorAddress, is a system-level address (TRUE) or a physical address (FALSE). If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.
Volatile | boolean |
Description | string | Volatile is a property that indicates whether this memory is volatile or not.
AdditionalErrorData | uint8[] |
Deprecated | string | CIM_MemoryError.AdditionalErrorData

Description

string

An array of octets holding additional error information. An example is ECC Syndrome or the return of the check bits if a CRC-based ErrorMethodology is used. In the latter case, if a single bit error is recognized and the CRC algorithm is known, it is possible to determine the exact bit that failed. This type of data (ECC Syndrome, Check Bit or Parity Bit data, or other vendor supplied information) is included in this field. If the ErrorInfo property is equal to 3, "OK", then AdditionalErrorData has no meaning.

MappingStrings | string | MIF.DMTF|Memory Device|005.18, MIF.DMTF|Physical Memory Array|001.13
OctetString | boolean | true
ErrorData | uint8[] |
ArrayType | string | Indexed
Deprecated | string | CIM_MemoryError.ErrorData
Description | string | Data captured during the last erroneous mebmory access. The data occupies the first n octets of the array necessary to hold the number of bits specified by the ErrorTransferSize property. If ErrorTransferSize is 0, then this property has no meaning.
