Abstract
A non-volatile dual in-line memory module (NVDIMM) instantiates first and second partitions of non-volatile memory. The first partition is reserved and is not accessible to an operating system instantiated. The second partition is accessible to the operating system. A processor detects a first bad memory location in the second partition, stores a first system physical address of the first bad memory location to a system bad memory locations list, and stores a first DIMM physical address of the first bad memory location to a first NVDIMM bad memory locations list in the first partition.
