Abstract: A system can respond to detection or prediction of an uncorrectable error (UE) in memory based on fault-aware analysis. The fault-aware analysis enables the system to generate a determination of a specific hardware element of the memory that is faulty. In response to detection of an error, the system can correlate a hardware configuration of the memory device with historical data indicating memory faults for hardware elements of the hardware configuration. Based on a determination of the specific component that likely caused the UE, the system can identify a region of memory associated with the detected UE and mirror the faulty region to a reserved memory space of the memory device for access to data of the faulty region.

Abstract: A system can predict what pages of memory the system should offline based on identification of how correctable error patterns correlate to the memory architecture. The failure prediction can account for the circuit-level architecture of the memory rather than the mere number or frequency of correctable errors. A controller correlates the hardware configuration of the memory with historical error data, and generates an estimate of pages for a host operating system (OS) to offline based on predicting uncorrectable errors (UEs).
