Abstract
A memory controller uses a history of the rows accessed by commands from a command queue in a command queue circuit to predict whether a second access performed immediately after the command queue becomes empty will be to a same row as a first access performed immediately before the command queue became empty. When the second access is predicted to be to a different row, the row corresponding to the first access is closed in response to the command queue becoming empty. When the second access is predicted to be to the same row, the row corresponding to the first access is not closed in response to the command queue becoming empty.
