摘要: A method and system for refreshing DRAM having a plurality of banks, each the banks including rows includes dividing all in into groups n wherein is an integer greater than or equal to 1. threshold available retention time group determined. Each row refreshed. Refreshing one bank determining whether refresh operation conflicts with access where located. If there conflict, then it determined perform current bank. operation, continued. recess performance improved.
