Abstract
A memory system and method includes a unidirectional downstream bus coupling write data from a memory controller to several memory devices, and a unidirectional upstream bus coupling read data from the memory devices to the memory controller. The memory devices each include a write buffer for storing the write data until the respective memory device is no longer busy processing read memory requests. The downstream bus may also be used for coupling memory commands and/or row and column addresses from the memory controller to the memory devices.
