Capabilities and management of Memory-related LogicalDevices.

Local properties

uint64 ErrorResolution

Deprecated! 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.

uint16 ErrorAccess

Deprecated! 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.

ValueMap Values
1 Other
2 Unknown
3 Read
4 Write
5 Partial Write

boolean Volatile

Volatile is a property that indicates whether this memory is volatile or not.

boolean CorrectableError

Boolean indicating that the most recent error was correctable. If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.

uint8[] AdditionalErrorData

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.

boolean SystemLevelAddress

Deprecated! 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.

uint16 ErrorDataOrder

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 Values
0 Unknown
1 Least Significant Byte First
2 Most Significant Byte First

uint32 ErrorTransferSize

Deprecated! 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.

uint64 ErrorAddress

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.

uint8[] ErrorData

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.

uint64 EndingAddress

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.

string OtherErrorDescription

Deprecated! 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.

uint16 ErrorInfo

Deprecated! 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 Values
1 Other
2 Unknown
3 OK
4 Bad Read
5 Parity Error
6 Single-Bit Error
7 Double-Bit Error
8 Multi-Bit Error
9 Nibble Error
10 Checksum Error
11 CRC Error
12 Undefined
13 Undefined
14 Undefined

datetime ErrorTime

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.

string ErrorMethodology

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.

uint64 StartingAddress

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.
