Method and apparatus for scalable exclusive access management in memory systems

Abstract

This disclosure provides systems, methods, and devices for memory systems that support enhanced exclusive read and write operations and scalable exclusive monitor architectures. In one 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 of the one or more NIUs including an exclusive monitor configured to monitor exclusive accesses to shared memory addresses for a corresponding request node. 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 coupled to each NIU and to each home node and 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.
