This disclosure provides methods, devices, and systems for memory management. The present implementations more specifically relate to techniques for providing shared memory services over a Compute Express Link (CXL) fabric. In some aspects, a memory management system may include a shared memory (SM) manager and multiple SM libraries each associated with a respective host device coupled to a shared memory via a CXL fabric. In some implementations, an SM library may negotiate read or write 'locks' with the SM manager for an object in shared memory, where a read-lock grants the associated host device read access to the object and a write-lock grants the associated host device write access to the object. In some implementations, the SM manager may grant any number of read-locks, but only one write-lock, to any object in shared memory so that the object becomes immutable once the host device relinquishes its write-lock for the object.
