1. A memory module comprising:

  • a plurality of memory devices, each memory device having a corresponding load; and

    a circuit electrically coupled to the plurality of memory devices and configured to be electrically coupled to a memory controller of a computer system, the circuit selectively isolating one or more of the loads of the memory devices from the computer system, the circuit comprising logic which translates between a system memory domain of the computer system and a physical memory domain of the memory module, wherein the system memory domain is compatible with a first number of chip selects, and the physical memory domain is compatible with a second number of chip selects equal to twice the first number of chip selects.
