Memory Sub-System with Computer Express Link Connection to Access Random Access Memory Cells Connected via Computer Express Link Fabric in Implementing Storage Services

A system, comprising:

• a computer express link fabric;
• a plurality of memory devices having random access memory cells;
• and
• a memory sub-system having non-volatile memory cells to provide a storage space, wherein each of the plurality of memory devices and the memory sub-system is connected to the computer express link fabric via a separate connection;
• wherein the memory sub-system is configured to use a portion of the random access memory cells, in the plurality of memory devices but outside of the memory sub-system, in processing a storage access request received via the computer express link fabric.

A memory sub-system, comprising:

• a host interface configured to operate on a computer express link connection;
• non-volatile memory cells configured to provide a persistent storage space addressable over the host interface via logical block addressing addresses;
• and
• at least one processing device configured to:
• retrieve a storage access request via the host interface and over the computer express link connection to a computer express link fabric;
• allocate a portion of random access memory cells connected to the memory sub-system via the computer express link fabric;
• send, via the host interface and over the computer express link connection, one or more memory access requests into the computer express link fabric to access the portion of the random access memory cells;
• and
• process the storage access request based on one or more responses to the one or more memory access requests.
