Abstract
In a hybrid memory system that includes a host memory controller and a non-volatile memory DIMM, where the DIMM is coupled to the host memory controller by a memory bus, the DIMM includes non-volatile memory, a DIMM bus adapter, and a local memory controller, the local memory controller is configured to control memory accesses within the DIMM, the DIMM bus adapter is configured to adapt the local memory controller to the bus for memory communications with the host memory controller in accordance with a bus protocol, bus resiliency may be provided by: discovering, by the DIMM bus adapter, a memory error in the DIMM; providing, by the DIMM bus adapter to the host memory controller, an indication of an error by emulating a hardware error native to the bus protocol; and performing, by the host memory controller, one or more resiliency measures responsive to the indication of the error.

12. A hybrid memory system for providing bus resiliency, the hybrid memory system comprising:
-
a host memory controller; a non-volatile memory DIMM (Dual Inline Memory Module); and a memory bus coupling the host memory controller to the DIMM, wherein; the DIMM is coupled to the host memory controller and comprises non-volatile memory, a DIMM bus adapter, and a local memory controller; the local memory controller is configured to control memory accesses within the DIMM; and the DIMM bus adapter is configured to; adapt the local memory controller to the bus for memory communications with the host memory controller in accordance with a bus protocol; discover a memory error in the DIMM; and provide, to the host memory controller, an indication of an error by emulating a hardware error native to the bus protocol; and the host memory controller is further configured to perform one or more resiliency measures responsive to the indication of the error. - View Dependent Claims (13, 14, 15, 16, 17)

18. A hybrid memory system for providing bus resiliency, the hybrid memory system comprising:
-
a host memory controller; a non-volatile memory DIMM (Dual Inline Memory Module); a memory bus coupling the host memory controller to the DIMM; and a driver for the DIMM, wherein; the DIMM is coupled to the host memory controller and comprises non-volatile memory, a DIMM bus adapter, and a local memory controller; the local memory controller is configured to control memory accesses within the DIMM; and the DIMM bus adapter is configured to; adapt the local memory controller to the bus for memory communications with the host memory controller in accordance with a bus protocol; discover a memory error in the DIMM; and provide, to the host memory controller, an indication of an error without emulating a hardware error native to the bus protocol; and the driver is configured to discover the indication of the error and perform one or more resiliency measures responsive to the indication of the error. - View Dependent Claims (19, 20)
