## Class Properties

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
CorrectableError | boolean |
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
ErrorAccess | uint16 |
Description | string | An integer enumeration indicating the memory access operation that caused the last error. The type of error MUST be 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 | 0, 1, 2, 3, 4
Values | string | Unknown, Other, Read, Write, Partial Write
ErrorDataOrder | uint16 |
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 |
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.
MappingStrings | string | MIF.DMTF|Memory Device|005.12, MIF.DMTF|Physical Memory Array|001.8
ModelCorrespondence | string | CIM_Memory.OtherErrorDescription
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Values | string | Unknown, Other, OK, Bad Read, Parity Error, Single-Bit Error, Double-Bit Error, Multi-Bit Error, Nibble Error, Checksum Error, CRC Error
ErrorResolution | uint64 |
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 |
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 |
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 |
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 | Specifies the address of the 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.
Key | boolean | true
MappingStrings | string | MIF.DMTF|Memory Device|005.19, MIF.DMTF|Physical Memory Array|001.14
Override | string | StartingAddress
SystemLevelAddress | boolean |
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.
AdditionalErrorData | uint8[] |
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
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.
MappingStrings | string | MIF.DMTF|Physical Memory Array|001.12
OctetString | boolean | true
