Abstract
The memory banks of a memory device are arranged and operated in groups and the groups are further arranged and operated as clusters of these groups. Successive accesses to banks that are within different bank group clusters may be issued at a first time interval. Successive accesses to banks that are within different bank groups within the same cluster can be issued no faster than a second time interval. And, successive accesses to banks that are within the same bank group may be issued no faster than a third time interval. The memory banks of a memory device may have multiple rows open at the same time. The rows that can be open at the same time is determined by the rows that are already open. These memory banks are also arranged and operated in groups that have three different minimum time intervals.
