Memory Training Results Corresponding To A Plurality Of Memory Modules

An apparatus for improving memory training results corresponding to a plurality of memory modules, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that when executed cause the apparatus to carry out the steps of:

• detecting, by a training controller, a hardware configuration change upon initiating a boot sequence of a system that includes the plurality of memory modules;
• generating for a plurality of training iterations, by the training controller, reference training values corresponding to aligning of a data strobe (DQS) signal with a data valid window of data (DQ) lines of the plurality of memory modules;
• identifying for each training iteration, by the training controller, any outer values within the reference training values generated for that training iteration;
• eliminating, by the training controller, the identified outer values from the reference training values;
• generating, by the training controller, a final reference training value based on an average of the remaining reference training values;
• and
• using, by the training controller, the final reference training value as the DQ-DQS timing value for the boot sequence of the system.

A computer program product for improving memory training results corresponding to a plurality of memory modules, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions capable, when executed, of causing a computer to carry out the steps of:

• detecting, by a training controller, a hardware configuration change upon initiating a boot sequence of a system that includes the plurality of memory modules;
• generating for a plurality of training iterations, by the training controller, reference training values corresponding to aligning of a data strobe (DQS) signal with a data valid window of data (DQ) lines of the plurality of memory modules;
