Runtime sparing for uncorrectable errors based on fault-aware analysis

A system for handling memory failure, comprising:

• a host hardware platform including a central processing unit (CPU) and multiple memory devices;
• and
• a controller coupled to the memory devices, the controller to detect an uncorrectable error (UE) in data from a memory device, correlate a hardware configuration of the memory device with historical data indicating memory faults for hardware elements of the hardware configuration to identify a faulty region of memory associated with the UE and mirror the faulty region at runtime to a reserved memory space of the memory device for access to data of the faulty region, wherein the controller is to mirror the faulty region only in response to a write access request to the faulty region.
