Abstract: In an example, a system includes a memory controller that includes a plurality of memory components. The system also includes a memory controller configured to receive a plurality of memory settings to be applied to the plurality of memory components. The memory controller is configured to, based on the received memory settings, transmit a first command to the plurality of memory components, the first command causing each memory component of the plurality of memory components to be configured to a first memory setting. The memory controller is configured to, based on the received memory settings, transmit a second command to a subset of the plurality of memory components after transmitting the first command, the second command causing each memory component of the subset to be configured to a second memory setting.

Abstract: A method, system and memory controller are provided for implementing signal integrity fail recovery and mainline calibration for Dynamic Random Access Memory (DRAM). After identifying a failed DRAM, the DRAM is marked as bad and taken out of mainline operation. Characterization tests and periodic calibrations are run to evaluate optimal settings and to determine if the marked DRAM is recoverable. If recoverable, the marked DRAM chip is redeployed. If unrecoverable, error reporting is provided to the user.

Abstract: Correction of duty cycle distortion of DQ and DQS signals between a memory controller and a memory is corrected by determining a duty cycle correction factor. The duty cycle distortion is corrected by applying the duty cycle correction factor to the plurality of differential DQS signals. The duty cycle distortion is corrected across a plurality of differential DQS signals between the memory controller and the bursting memory.
