Aspects include computing devices, systems, and methods for reorganizing the storage of data in memory to energize less than all of the memory devices of a memory module for read or write transactions. The memory devices may be connected to individual select lines such that a re-order logic may determine the memory devices to energize for a transaction according to a re-ordered memory map. The re-order logic may re-order memory addresses such that memory address provided by a processor for a transaction are converted to the re-ordered memory address according to the re-ordered memory map without the processor having to change its memory address scheme. The re-ordered memory map may provide for reduced energy consumption by the memory devices, or a balance of energy consumption and performance speed for latency tolerant processes.
