Abstract: Systems and methods to respond to schedule commands at a memory controller are disclosed. A transmission error between a first memory controller port and a first redrive device may be detected. A first corrective action may be initiated at the first memory controller port in response to the detection of the transmission error. A particular method may include determining that a second memory controller port initiated a second corrective action. Incoming read commands may be distributed based on a comparison of the first corrective action and the second corrective action.

Abstract: 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.

Abstract: Systems and methods to respond to error detection are provided. A particular method may include issuing a first command to a first redrive device and a second command to a second redrive device. The method may also include reissuing the second command to the second redrive device in response to detecting a transmission error between a memory controller and the second redrive device. The method may further include storing at a first buffer first data that is received from the first redrive device in response to the first command. The method may include storing at a second buffer second data that is received from the second redrive device in response to the reissued second command. The method also may include merging the second data with the first data.
