Hardware command training for memory using read commands

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 memory controller into a mode wherein a column access strobe is active for a single clock cycle;
• b) programming a programmable delay line of said column access strobe with a delay value;
• c) initializing said memory module;
• d) sending a read command to said memory module;
• e) counting a number of data strobe signals sent by said memory module in response to said read command;
• and
• f) determining whether said memory module is in a pass state or an error state based on a result of said counting.

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 memory controller into a mode wherein a column access strobe is active for a single clock cycle;
• b) programming a programmable delay line of said column access strobe with a delay value;
• c) initializing said memory module;
• d) sending a read command to said memory module;
• e) counting a number of data strobe signals sent by said memory module in response to said read command;
• and
• f) determining whether said memory module is in a pass state or an error state based on a result of said counting.
