摘要： A compressed replay buffer in a first electronic unit of an electronic system holds commands in a table. As commands are transmitted from the first electronic unit to a second electronic unit, the command, along with associated data, command type, and the like are stored in a row in the table. No rows in the table contain “dead cycles” to indicate that no command was sent on a particular cycle on a bus over which the commands were transmitted. The second electronic unit may request that the first electronic unit replay some number of commands. In response, the first electronic unit uses commands in the compressed replay buffer, along with required timings stored on the first electronic unit, to replay the number of commands requested.

摘要： Systems and methods to respond to error detection are provided. First data may be received at a first memory controller port in response to a read command issued from the first memory controller port. The read command may be issued as a second read command from a second memory controller port after determining that the first data contains a first uncorrectable error. Second data may be received at the second memory controller port in response to the second read command. A repair write command may be issued from the first memory controller port after determining that the second data does not contain any errors. The repair write command may initiate writing the second data from the first memory controller port.

摘要： Systems and methods to manage memory refreshes at a memory controller are disclosed. A method includes determining, at a memory controller device, that a number of transmission errors between a memory controller port and a memory redrive device exceeds an error threshold. The method may include initiating a first link retraining process between the memory controller port and the memory redrive device. The method may further include placing one or more dynamic random access memory modules associated with the memory redrive device in a self-refresh mode. The method may also include removing the one or more dynamic random access memory modules from the self-refresh mode after the link retraining process has completed. The method may further include enabling overlapping refreshes of the one or more dynamic random access memory modules.

摘要： Read commands on a mirrored memory computer system are scheduled by utilizing information about pending memory access requests. A conflict queue is configured to track a read/write queue associated with each of a plurality of memory ports on the mirrored memory system. The conflict queue determines a predicted latency on each memory port based on the contents of each of the read/write queues. A compare logic unit is coupled to the conflict queue, wherein the compare logic unit compares a predicted latency of a primary memory and a mirrored memory and schedules read commands to the memory port with the lowest predicted latency.
