Abstract: A method, apparatus, and system are described. In one embodiment, the method comprises a chipset receiving a plurality of memory requests, wherein each memory request comprises one or more micro-commands that each require one or more memory clock cycles to execute, and scheduling the execution of each of the micro-commands from more than one of the plurality of memory requests in an order to reduce the number of total memory clock cycles required to complete execution of the more than one memory requests.

Abstract: The invention comprises an apparatus and method of prefetching from a memory device having interleaved channels. The chipset prefetcher comprises a stride detector to detect a stride in a stream, a prefetch injector to insert prefetches onto the memory device, a channel mapper to map the prefetches to each channel of the memory device, a scheduler to schedule the prefetches onto the memory device in a DRAM-state aware manner, a throttling heuristic to scale the number of prefetches, and a prefetch data buffer to store prefetch data. The method of prefetching comprises tracking the state of streams, detecting a stride on one of the streams, selecting the stream with the stride for prefetch injection, enqueueing prefetches from the selected stream, mapping the prefetches to each of the interleaved channels, injecting the prefetches from the selected stream into each of the interleaved channels, and scheduling the prefetches onto the memory device in a DRAM-state aware manner.

Abstract: A method to deterministically shut down memory devices in response to a system warm reset has been disclosed. One embodiment of the method includes causing a first type of reset in a number of memory devices in a system in response to a second type of reset in the system being initiated if the memory devices are not initialized and enabling a deterministic shutdown mode in a memory controller, which is coupled to the memory devices, after the memory devices have been initialized. Other embodiments are described and claimed.
