Abstract
A method and apparatus for controlling access to a multi-bank memory system. Multiple bank/row activation requests are presented by processes or systems seeking access to the memory. One of the banks of the memory is selected to be the target of a next bank/row activation request. Then, one of the requests corresponding to the chosen bank is selected and issued as the next request. Requests may be conditionally and iteratively selected until one is found whose target row corresponds to a currently active row in the target bank.
