Abstract
A method for performing refresh operations is disclosed. In response to a completion of a memory operation, a determination is made whether or not a refresh backlog count is greater than a first predetermined value. In a determination that the refresh backlog count is greater than the first predetermined value, a refresh operation is performed as soon as possible. In a determination that the refresh backlog count is not greater than the first predetermined value, a refresh operation is performed after a delay of an idle count value.
