Abstract
A computer system may include a system memory, an active device configured to access data stored in the system memory, where the active device includes a cache configured to store data accessed by the active device, an address network for conveying address packets between the active device and the system memory, and a data network for conveying data packets between the active device and the system memory. An access right corresponding to a given block allocated in the cache transitions in response to a corresponding data packet being received by the cache. An ownership responsibility for the given block transitions in response to a corresponding address packet being received by the cache. The access right transitions at a different time than the ownership responsibility transitions. The cache is configured to inhibit receipt of the corresponding data packet based on a value of a timestamp associated with the corresponding data packet.
