Memory Module Read Training via Partial Data Pin Activation

The patent divides the data pins into multiple groups and assigns different group identifiers to each group. During read training, only one group of pins is activated at a time to transmit training signals, while other groups remain inactive. This segmentation allows timing calibration to be performed on subsets of pins rather than all pins simultaneously, reducing overall power consumption while maintaining calibration accuracy for each group.

The patent implements partial action by activating only a portion of the data pins (one group at a time) during read training operations instead of all data pins. The training signal is transmitted through selected pins identified by group identifiers, enabling timing calibration to be performed with partial pin activation, thereby reducing power consumption while still achieving the necessary timing information.

The patent segments data pins into multiple groups with distinct group identifiers and implements corresponding receiving units in the memory controller. Each receiving unit is configured to receive training signals from specific pin groups. This segmentation organizes the complex training operation into manageable segments, reducing the overall device complexity while ensuring complete timing information is obtained across all pin groups through systematic sequential processing.

The patent applies partial action by performing read training operations on one pin group at a time rather than all pins simultaneously. The memory controller sequentially activates different pin groups identified by group identifiers, obtaining timing information from each group in turn. This approach reduces training operation complexity by breaking down the comprehensive training process into simpler, manageable partial operations.
