Abstract
Uncontested priority is provided to out-of-order data transfers over in-order data transfers on a data bus shared by a plurality of memory requesters. By always granting priority to out-of-order transfers such as deferred read data transfers over in-order transfers such as write and/or cache-to-cache data transfers, it is assured that no newer command or transaction ever negatively affects the latency of an older command or transaction.
