Obtaining data mask mapping information

An apparatus, comprising:

• a memory controller having a hardwired selection device to program the memory controller with a data mask mapping scheme, the data mask mapping scheme to associate at least one data mask bit with at least one data chunk in a memory module;
• and
• an output to be coupled to the memory module.

An apparatus, comprising:

• a memory controller including a storage device having information to indicate a data mask mapping scheme for the memory controller;
• and
• an output coupled to the memory module.

A system, comprising:

• a memory module to use at least one data mask mapping scheme to associate at least one data mask bit with at least one data chunk;
• a memory controller coupled with the memory module, the memory controller to be programmed with the at least one data mask mapping scheme used in the memory module.

A machine-readable medium that provides instructions, which when executed by a machine, causes the machine to perform operations comprising:

• obtaining, from within a memory system, information to indicate a data mask mapping scheme to be used in a memory module in the memory system;
• and
• determining the data mask mapping scheme based on the information.
