Abstract

This disclosure provides systems, methods, and devices for memory systems that support enhanced exclusive access fairness operations for scalable exclusive monitor architectures. In a first aspect, device includes a processing system that includes one or more shared memory devices and one or more request nodes. The processing system also includes one or more network interface units (NIUs), each NIU including an exclusive monitor configured to monitor exclusive accesses to shared memory addresses for a corresponding request node and including a timeout register for the exclusive monitor configured to control exclusive access fairness. The processing system includes one or more home nodes coupled to a corresponding shared memory device of the one or more shared memory devices. The processing system further includes an interconnect configured to couple the one or more request nodes to the one or more shared memory devices. Other aspects and features are also claimed and described.
