Abstract
A memory subsystem includes a group of memory devices connected to an address bus. The memory subsystem includes logic to uniquely map a physical address of a memory access command to each memory device of the group. Thus, each physical address sent by an associated memory controller uniquely accesses a different row of each memory device, instead of being mapped to the same or corresponding row of each memory device.
