Summary:Apparatus and methods of increasing the data rate and bandwidth of system memory including stacked memory device dice. The system memory includes a memory device having a plurality of memory device dice in a stacked configuration, a memory controller coupled to the stacked memory device dice, and a partitioned data bus. The memory device dice each include one, two, or more groups of memory banks. By configuring each memory device die to deliver all of its bandwidth over a different single partition of the data channel, the system memory can achieve an increased data rate and bandwidth without significantly increasing costs over typical system memory configurations that include stacked memory device dice.
