1100.0050.0001.0020 This attribute defines the failure modes of the memory device when the memoryDeviceStatus attribute is not ok(3). It is a bit field that can be used to report more than one type of failure mode by using a combination of the defined bit masks. **NOTE: This attribute replaces the memory device error count attributes. When the memoryDeviceStatus attribute is not ok(3), this attribute should be used to determine the reason for that instead of the error count attributes.
