Multi-dimensional hardware data training between memory controller and memory

A computer readable storage medium having stored thereon, computer executable instructions that, if executed by a computer system cause the computer system to perform a method of training a command signal for a memory module, said method comprising:

• a) programming a delay line of a data strobe with a delay value and programming a reference voltage with a voltage value;
• b) writing a data bit pattern to said memory module wherein said data bit pattern is of a first plurality of unique data bit patterns;
• c) reading back said data bit pattern and comparing a result thereof with said data bit pattern;
• d) determining whether said memory module is in a passing state or an error state based on said comparing;
• e) repeating said b)-d) with another data bit pattern of said first plurality of data bit patterns;
• f) reprogramming said delay line with another delay value and reprogramming said reference voltage with another voltage value;
• and
• g) repeating said b)-f).

A system comprising:

• a processor coupled to a computer readable storage media using a bus and executing computer readable code which causes the computer system to perform a method of training a command signal for a memory module, said method comprising:
• a) programming a delay line of a data strobe with a delay value and programming a reference voltage with a voltage value;
• b) writing a data bit pattern to said memory module wherein said data bit pattern is of a first plurality of unique data bit patterns;
• c) reading back said data bit pattern and comparing a result thereof with said data bit pattern;
• d) determining whether said memory module is in a passing state or an error state based on said comparing;
• e) repeating said b)-d) with another data bit pattern of said first plurality of data bit patterns;
• f) reprogramming said delay line with another delay value and reprogramming said reference voltage with another voltage value;
• and
• g) repeating said b)-f).
