Memory system with content-addressable entries supporting scalable, low overhead, in-flight establishment and retirement of resource-based linked lists, and related methods and computer-readable media

Abstract

A memory system with content-addressable entries supporting scalable, low overhead, in-fight establishment and retirement of resource-based linked lists, and related methods of operation and computer-readable media. The memory system can be used to track and establish an ordering of in-flight instances of access to a resource through a linked-list of content-addressable entries established in the memory system corresponding to such resource. Entries in the memory system that represent instances of access to a given resource can each be established as part of a linked list associated for the given resource to track a priority order for multiple instances of access the resource and then retired when an instance of access has been completed as part of a tracking system, such as to avoid hazards. The memory system provides a way to establish entries in a linked list for in flight instances of access to a resource for ordering and tracking.
