Fault-resilient software-defined persistent memory system

A volatile memory system, including:

• at least one memory device that defines a memory address range;
• and
• a memory controller subsystem that is coupled to the at least one memory device and that is configured to:
• receive a write request to write data to a Software-Defined Persistent Memory (SDPM) zone that is defined in the memory address range such that the SDPM zone at least partially overlaps with a Fault Resilient Memory (FRM) primary data storage zone that is defined in the memory address range;
• write, in response to the write request, the data to the SDPM zone that at least partially overlaps with the FRM primary data storage zone;
• and
• write, to an FRM mirrored data storage zone that is defined in the memory address range, the data that was written to the SDPM zone that at least partially overlaps with the FRM primary data storage zone.

A method for providing a fault-resilient software-defined persistent memory system in a computing device, comprising:

• receiving, by a memory controller subsystem a write request to write data to a Software-Defined Persistent Memory (SDPM) zone that is defined in a memory address range provided by at least one memory device in a volatile memory system such that the SDPM zone at least partially overlaps with a Fault Resilient Memory (FRM) primary data storage zone that is defined in the memory address range;
• writing, by the memory controller subsystem, in response to the write request, the data to the SDPM zone that at least partially overlaps with the FRM primary data storage zone;
• and
• writing, by the memory controller subsystem to a FRM mirrored data storage zone that is defined in the memory address range, the data that was written to the SDPM zone that at least partially overlaps with the FRM primary data storage zone.
