NameData TypeValue
CorrectableErrorboolean
DeprecatedstringCIM_MemoryError.CorrectableError
DescriptionstringBoolean indicating that the most recent error was correctable. If the ErrorInfo property is equal to 3, "OK", then this property has no meaning.
MappingStringsstringMIF.DMTF|Physical Memory Array|001.8
EndingAddressuint64
DescriptionstringThe 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.
MappingStringsstringMIF.DMTF|Memory Array Mapped Addresses|001.4, MIF.DMTF|Memory Device Mapped Addresses|001.5
PUnitstringbyte * 10^3
UnitsstringKiloBytes
ErrorAccessuint16
DeprecatedstringCIM_MemoryError.ErrorAccess
DescriptionstringAn 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.
MappingStringsstringMIF.DMTF|Physical Memory Array|001.10
ValueMapstring1, 2, 3, 4, 5
ValuesstringOther, Unknown, Read, Write, Partial Write
ErrorAddressuint64
DeprecatedstringCIM_MemoryError.StartingAddress
DescriptionstringSpecifies 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.
MappingStringsstringMIF.DMTF|Memory Device|005.19, MIF.DMTF|Physical Memory Array|001.14
ErrorDataOrderuint16
DeprecatedstringCIM_MemoryError.ErrorDataOrder
DescriptionstringThe 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.
ValueMapstring0, 1, 2
ValuesstringUnknown, Least Significant Byte First, Most Significant Byte First
ErrorInfouint16
DeprecatedstringCIM_MemoryError.ErrorInfo
DescriptionstringAn 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.
MappingStringsstringMIF.DMTF|Memory Device|005.12, MIF.DMTF|Physical Memory Array|001.8
ModelCorrespondencestringCIM_Memory.OtherErrorDescription
ValueMapstring1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
ValuesstringOther, Unknown, OK, Bad Read, Parity Error, Single-Bit Error, Double-Bit Error, Multi-Bit Error, Nibble Error, Checksum Error, CRC Error, Undefined, Undefined, Undefined
ErrorMethodologystring
DescriptionstringErrorMethodology 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.
MappingStringsstringMIF.DMTF|Physical Memory Array|001.7
OverridestringErrorMethodology
ErrorResolutionuint64
DeprecatedstringCIM_MemoryError.ErrorResolution
DescriptionstringSpecifies 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.

PUnitstringbyte
UnitsstringBytes
ErrorTimedatetime
DeprecatedstringCIM_MemoryError.ErrorTime
DescriptionstringThe 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.
ErrorTransferSizeuint32
DeprecatedstringCIM_MemoryError.ErrorTransferSize
DescriptionstringThe 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.
MappingStringsstringMIF.DMTF|Physical Memory Array|001.11
PUnitstringbit
UnitsstringBits
OtherErrorDescriptionstring
DeprecatedstringCIM_MemoryError.OtherErrorDescription
DescriptionstringFree 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.
ModelCorrespondencestringCIM_Memory.ErrorInfo
StartingAddressuint64
DescriptionstringThe 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.
MappingStringsstringMIF.DMTF|Memory Array Mapped Addresses|001.3, MIF.DMTF|Memory Device Mapped Addresses|001.4
PUnitstringbyte * 10^3
UnitsstringKiloBytes
SystemLevelAddressboolean
DeprecatedstringCIM_MemoryError.SystemLevelAddress
DescriptionstringBoolean 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.
Volatileboolean
DescriptionstringVolatile is a property that indicates whether this memory is volatile or not.
AdditionalErrorDatauint8[]
DeprecatedstringCIM_MemoryError.AdditionalErrorData
DescriptionstringAn 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.
MappingStringsstringMIF.DMTF|Memory Device|005.18, MIF.DMTF|Physical Memory Array|001.13
OctetStringbooleantrue
ErrorDatauint8[]
ArrayTypestringIndexed
DeprecatedstringCIM_MemoryError.ErrorData
DescriptionstringData 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.
