The Win32_CacheMemory class has these properties.
Type of access.
Array of octets that hold additional error information. An example is ECC Syndrome or the return of the check bits if a CRC-based error methodology 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, Parity Bit data, or other vendor supplied information) is included in this field. If the ErrorInfo property is equal to 3 (OK), then this property has no meaning.
An integer enumeration that defines the system cache associativity.
This value comes from the Associativity member of the Cache Information structure in the SMBIOS information.

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states.
