Abstract: A memory coherency controller. Responsive to a request including a request type and request memory address, relevant queues are examined for queued addresses matching the request memory address. Responsive to a request memory address matching at least one of the queued addresses, the request is rejected. Following a retry latency, the request is retried. When the address of a read request matches queued address in a store queue, at least one request in the store queue is prioritized higher than all other queued requests.
