Auto-precharge management in a controller

Abstract:

A system includes a queue and a controller. The queue receives a transactions from masters to access a memory component. The memory component includes a plurality of rows. The controller issues a command to access a row of the plurality of rows in response to receiving a first issued transaction. The first issued transaction is issued by a first master. The controller is configured to prevent issuing an auto-precharge command to keep the row associated with the first issued transaction open if a subsequent transaction in the queue from the first master accesses a same row as the first transaction. The controller is configured to prevent issuing the auto-precharge command to keep the row associated with the first issued transaction open if the controller receives data associated with keeping the row associated with the first issued transaction open.
