Abstract
A memory subsystem includes a multi-device package including multiple memory devices organized as multiple ranks of memory. A control unit for the memory subsystem sends a memory access command concurrently to some or all of the ranks of memory, and triggers some of all of the memory ranks that receive the memory access command to change on-die termination (ODT) settings. One of the ranks is selected to execute the memory access command, and executes the command while all ranks triggered to change the ODT setting have the changed ODT setting.
