Abstract
In one aspect, the invention describes a mechanism for refreshing multiple memory words (rows) per refresh cycle, the number of simultaneously refreshed rows being programmable by a small number of inputs. In another aspect, the invention discloses a mechanism for refreshing all banks or a programmable number of banks simultaneously in a multi-bank memory. In yet another aspect, the present invention describes a mechanism for refreshing a programmable multiple memory rows and a programmable multiple banks simultaneously.
