A memory module, which may include volatile memory or nonvolatile memory, or both, may be configured to communicate with a host device via one interface and to communicate with another memory module using a different interface. Memory modules may thus be added or removed from a system without impacting a PCB-based bus to the host, and memory modules may communicate with one another without accessing a bus to the host. The host interface may be configured according to one protocol or standard, and other interfaces between memory modules may be configured according to other protocols or standards. |

Time to live for load commands
A memory sub-system configured to be responsive to a time to live requirement for load commands from a processor. For example, a load command issued by the processor (e.g., SoC) can include, or be associated with, an optional time to live parameter. The parameter requires that the data at the memory address be available within the time specified by the time to live parameter. When the requested data is currently in the lower speed memory (e.g., NAND flash) and not available in the higher speed memory (e.g., DRAM, NVRAM), the memory sub-system can determine that the data cannot be made available with the specified time and optionally skip the operations and return an error response immediately. |
