摘要： Mechanisms are provided for efficient storage of meta-bits within a system memory. The mechanisms combine an L/G bit and an SUE bit to form meta-bits. The mechanisms then determine the local/global state of a cache line on the first cycle of data. The mechanisms forward the data to the requesting cache, and the requesting cache may reissue the request globally based on the local/global state of the cache line. The mechanisms then determine the special uncorrectable error state of the cache line on the second or subsequent cycle of data. The mechanisms perform error processing regardless of whether the request was reissued globally.

摘要： A memory system and data processing system for controlling memory refresh operations in dynamic random access memories. The memory controller comprises logic that: tracks a time remaining before a scheduled time for performing a high priority, high latency operation a first memory rank of the memory system; responsive to the time remaining reaching a pre-established early notification time before the schedule time for performing the high priority, high latency operation, biases the re-order queue containing memory access operations targeting the plurality of ranks to prioritize scheduling of any first memory access operations that target the first memory rank. The logic further: schedules the first memory access operations to the first memory rank for early completion relative to other memory access operations in the re-order queue that target other memory ranks; and performs the high priority, high latency operation at the first memory rank at the scheduled time.

摘要： Techniques for performing refresh operations is disclosed. In response to a completion of a memory operation, a determination is made whether or not a refresh backlog count is greater than a first predetermined value. In a determination that the refresh backlog count is greater than the first predetermined value, a refresh operation is performed as soon as possible. In a determination that the refresh backlog count is not greater than the first predetermined value, a refresh operation is performed after a delay of an idle count value.

摘要： A memory configured to provide a write requestor with a direct write programming interface to a disk device. A first persistent memory is configured for designating at least a portion its memory locations as central processing unit (CPU) load storable memory. The first persistent memory is also configured for receiving write data from the write requestor, for storing the write data in the CPU load storable memory, and for returning a write completion message to the write requestor in response to the storing completing. The memory also includes a second persistent memory that includes the disk device, and a controller in communication with the first and second persistent memories. The controller is configured for detecting the storing of the write data to the CPU load storable memory and for copying the write data to the second persistent memory in response to detecting the storing of the write data.

摘要： A data processing system includes one or more processing units, a memory subsystem, and one or more input/output channel controllers, wherein each of the input/output channel controllers include the capability of speculative input/output execution. The speculative I/O execution technique according to the present invention may include several options. The speculative execution in the IOCC begins after receiving a raw address even though the operation can still be remotely retried. The programmed I/O latency time is reduced significantly due to the early speculative commencement of the IOCC operation. The IOCC may have to abort the speculative operation if a remote flow control retry is received. If, however, no retry is received then significant time is saved because the speculative operation proceeds.

摘要： A technique for memory command throttling in a partitioned memory subsystem includes accepting, by a master memory controller included in multiple memory controllers, a synchronization command. The synchronization command includes command data that includes an associated synchronization indication (e.g., a synchronization bit or bits) for each of the multiple memory controllers and each of the multiple memory controllers controls a respective partition of the partitioned memory subsystem. In response to receiving the synchronization command, the master memory controller forwards the synchronization command to the multiple memory controllers. In response to receiving the forwarded synchronization command each of the multiple memory controllers de-asserts an associated status bit. In response to receiving the forwarded synchronization command, each of the multiple memory controllers determines whether the associated synchronization indication is asserted. Each of the multiple memory controllers with the asserted associated synchronization indication then transmits the forwarded synchronization command to associated power control logic.
